Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation and Presentation	Principles of Consolidation and Presentation The accompanying consolidated financial statements have been prepared in accordance with US GAAP and include all of our accounts as well as accounts of the Partnership, subsidiary partnerships and our wholly owned Taxable REIT Subsidiary Lessee (“TRS Lessee”), 44 New England Management Company. All significant inter-company amounts have been eliminated. Consolidated properties are either wholly owned or owned less than 100% by the Partnership and are controlled by the Company as general partner of the Partnership. Properties owned in joint ventures are also consolidated if the determination is made that we are the primary beneficiary in a variable interest entity (“VIE”) or we maintain control of the asset through our voting interest in the entity.
Variable Interest Entities	Variable Interest Entities We evaluate each of our investments and contractual relationships to determine whether they meet the guidelines for consolidation. To determine if we are the primary beneficiary of a VIE, we evaluate whether we have a controlling financial interest in that VIE. An enterprise is deemed to have a controlling financial interest if it has i) the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance, and ii) the obligation to absorb losses of the VIE that could be significant to the VIE or the rights to receive benefits from the VIE that could be significant to the VIE. Control can also be demonstrated by the ability of a member to manage day-to-day operations, refinance debt and sell the assets of the partnerships without the consent of the other member and the inability of the members to replace the managing member. Based on our examination, there have been no changes to the operating structure of our legal entities during the three and six months ended June 30, 2023 and, therefore, there are no changes to our evaluation of VIE's as presented within our annual report presented on Form 10-K for the year ended December 31, 2022.
Noncontrolling Interest	Noncontrolling InterestWe classify the noncontrolling interests of our common units of limited partnership interest in HHLP (“Common Units”), and Long Term Incentive Plan Units (“LTIP Units”) as equity. LTIP Units are a separate class of limited partnership interest in the Operating Partnership that are convertible into Common Units under certain circumstances.
Investment in Hotel Properties	Investment in Hotel Properties Investments in hotel properties are recorded at cost. Improvements and replacements are capitalized when they extend the useful life of the asset. Costs of repairs and maintenance are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful life of up to 40 years for buildings and improvements, and two to seven years for furniture, fixtures and equipment. We are required to make subjective assessments as to the useful lives of our properties for purposes of determining the amount of depreciation to record on an annual basis with respect to our investments in hotel properties. These assessments have a direct impact on our net income because if we were to shorten the expected useful lives of our investments in hotel properties we would depreciate these investments over fewer years, resulting in more depreciation expense and lower net income on an annual basis. Identifiable assets, liabilities, and noncontrolling interests related to hotel properties acquired are recorded at fair value. Estimating techniques and assumptions used in determining fair values involve significant estimates and judgments. These estimates and judgments have a direct impact on the carrying value of our assets and liabilities which can directly impact the amount of depreciation expense recorded on an annual basis and could have an impact on our assessment of potential impairment of our investment in hotel properties. We consider a hotel to be held for sale when management and our independent trustees commit to a plan to sell the property, the property is available for sale, management engages in an active program to locate a buyer for the property and it is probable the sale will be completed within a year of the initiation of the plan to sell. We evaluate each disposition to determine whether we need to classify the disposition as discontinued operations. We generally include the operations of a hotel that was sold or a hotel that has been classified as held for sale in continuing operations unless the sale represents a strategic shift that will have a major impact on our future operations and financial results. We anticipate that most of our hotel dispositions will not be classified as discontinued operations as most will not fit this definition.

Such events or changes in circumstances include the following: •a significant decrease in the market price of a long-lived asset; •a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition; •a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, including an adverse action or assessment by a regulator; •an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset; •a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset; and •a current expectation that, it is more likely than not that, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. We review our portfolio on an ongoing basis to evaluate the existence of any of the aforementioned events or changes in circumstances that would require us to test for recoverability. In general, our review of recoverability is based on an estimate of the future undiscounted cash flows, excluding interest charges, expected to result from the property’s use and eventual disposition. These estimates consider factors such as expected future operating income, market and other applicable trends and residual value expected, as well as the effects of hotel demand, competition and other factors.

To reflect the correction of these immaterial errors, the Company is revising the previously issued consolidated financial statements for the three and six months ended June 30, 2022 in this Form 10-Q.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation and Presentation

The accompanying consolidated financial statements have been prepared in accordance with US GAAP and include all of our accounts as well as accounts of the Partnership, subsidiary partnerships and our wholly owned Taxable REIT Subsidiary Lessee (“TRS Lessee”), 44 New England Management Company. All significant inter-company amounts have been eliminated.

Consolidated properties are either wholly owned or owned less than 100% by the Partnership and are controlled by the Company as general partner of the Partnership. Properties owned in joint ventures are also consolidated if the determination is made that we are the primary beneficiary in a variable interest entity (“VIE”) or we maintain control of the asset through our voting interest in the entity.

Variable Interest Entities

We evaluate each of our investments and contractual relationships to determine whether they meet the guidelines for consolidation. To determine if we are the primary beneficiary of a VIE, we evaluate whether we have a controlling financial interest in that VIE. An enterprise is deemed to have a controlling financial interest if it has i) the power to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance, and ii) the obligation to absorb losses of the VIE that could be significant to the VIE or the rights to receive benefits from the VIE that could be significant to the VIE. Control can also be demonstrated by the ability of a member to manage day-to-day operations, refinance debt and sell the assets of the partnerships without the consent of the other member and the inability of the members to replace the managing member. Based on our examination, there have been no changes to the operating structure of our legal entities during the three and six months ended June 30, 2023 and, therefore, there are no changes to our evaluation of VIE's as presented within our annual report presented on Form 10-K for the year ended December 31, 2022.

Noncontrolling Interest

Noncontrolling InterestWe classify the noncontrolling interests of our common units of limited partnership interest in HHLP (“Common Units”), and Long Term Incentive Plan Units (“LTIP Units”) as equity. LTIP Units are a separate class of limited partnership interest in the Operating Partnership that are convertible into Common Units under certain circumstances.

Investment in Hotel Properties

Investments in hotel properties are recorded at cost. Improvements and replacements are capitalized when they extend the useful life of the asset. Costs of repairs and maintenance are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful life of up to 40 years for buildings and improvements, and two to seven years for furniture, fixtures and equipment. We are required to make subjective assessments as to the useful lives of our properties for purposes of determining the amount of depreciation to record on an annual basis with respect to our investments in hotel properties. These assessments have a direct impact on our net income because if we were to shorten the expected useful lives of our investments in hotel properties we would depreciate these investments over fewer years, resulting in more depreciation expense and lower net income on an annual basis.

Identifiable assets, liabilities, and noncontrolling interests related to hotel properties acquired are recorded at fair value. Estimating techniques and assumptions used in determining fair values involve significant estimates and judgments. These estimates and judgments have a direct impact on the carrying value of our assets and liabilities which can directly impact the amount of depreciation expense recorded on an annual basis and could have an impact on our assessment of potential impairment of our investment in hotel properties.

We consider a hotel to be held for sale when management and our independent trustees commit to a plan to sell the property, the property is available for sale, management engages in an active program to locate a buyer for the property and it is probable the sale will be completed within a year of the initiation of the plan to sell. We evaluate each disposition to determine whether we need to classify the disposition as discontinued operations. We generally include the operations of a hotel that was sold or a hotel that has been classified as held for sale in continuing operations unless the sale represents a strategic shift that will have a major impact on our future operations and financial results. We anticipate that most of our hotel dispositions will not be classified as discontinued operations as most will not fit this definition.

NOTE 1 - BASIS OF PRESENTATION (CONTINUED)

Based on the occurrence of certain events or changes in circumstances, we review the recoverability of the property’s carrying value. Such events or changes in circumstances include the following:

•a significant decrease in the market price of a long-lived asset;

•a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition;

•a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, including an adverse action or assessment by a regulator;

•an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset;

•a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset; and

•a current expectation that, it is more likely than not that, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.

We review our portfolio on an ongoing basis to evaluate the existence of any of the aforementioned events or changes in circumstances that would require us to test for recoverability. In general, our review of recoverability is based on an estimate of the future undiscounted cash flows, excluding interest charges, expected to result from the property’s use and eventual disposition. These estimates consider factors such as expected future operating income, market and other applicable trends and residual value expected, as well as the effects of hotel demand, competition and other factors. Other assumptions used in the review of recoverability include the holding period and expected terminal capitalization rate. If impairment exists due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property. We are required to make subjective assessments as to whether there are impairments in the values of our investments in hotel properties.

New Accounting Pronouncements

Revision of Prior Period Financial Statements

During the third quarter of 2022, the Company identified immaterial errors in its previously issued financial statements resulting from the incorrect amortization of accumulated other comprehensive income related to interest rate hedges. This occurred over the periods from 2019 through 2021, thereby overstating interest expense in those periods as well as impacting certain captions in the equity section of the consolidated balance sheet, including accumulated other comprehensive income, distributions in excess of net income, and noncontrolling interests.

In accordance with Staff Accounting Bulletin (“SAB”) No. 99, “Materiality,” and SAB No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company assessed the materiality of these misstatements both quantitatively and qualitatively and determined that these errors and the related impact did not, either individually or in the aggregate, materially misstate previously issued consolidated financial statements. To reflect the correction of these immaterial errors, the Company is revising the previously issued consolidated financial statements for the three and six months ended June 30, 2022 in this Form 10-Q.
