Subsequent Events [Abstract]
Subsequent Events	15.Subsequent Events Subsequent to December 31, 2019, we acquired or were under contract to acquire 14 self-storage facilities (four in Ohio, three in California, two each in New York and Tennessee and one each in Indiana, Massachusetts, and Nebraska) with 1.1 million net rentable square feet, for $245.3 million. On January 24, 2020, we completed a public offering of €500 million ($551.6 million) aggregate principal amount of senior notes bearing interest at an annual rate of 0.875% and maturing on January 24, 2032. Interest on the senior notes is payable annually, commencing January 24, 2021. In connection with the offering, we incurred a total of $6.4 million in costs. As we reported in an SEC form 8-K on February 14, 2020, we submitted a non-binding proposal to acquire 100% of the issued stapled securities of National Storage REIT (“NSR”), an Australia-based publicly-traded REIT (ASX:NSR) that owns and operates 167 self-storage facilities in Australia and New Zealand, for a cash purchase price of A$2.40 per share. Our proposal was subject to a number of conditions, including due diligence. Any transaction would be subject to processes for acquisition of widely held entities under Australian law, including securityholder approval. There is no assurance that Public Storage will reach a definitive agreement or consummate a transaction with NSR or that if such an agreement is reached, it will be on terms consistent with our non-binding proposal.
