I like how streamlined check in was -I received an email 3 days before, as promised, with absolutely no-hassle , easy-to-follow instructions. The place always smelled clean and I personally liked that I very rarely ran into other people. The location was great-easy access to the metro and walking distance from the National Mall. The Wonder app was useful to know what was nearby in the neighborhood and how to take advantage of the amenities. The size of the room was amazing and the kitchenette was a plus-very modern. Sonder met all of my expectations and then some.
