We came for one night when passing through Washington DC. The apartment was perfect for our needs. For example, when it was too hot outside to walk around, we decided to stay in the apartment until nightfall. The apartment was cool (air conditioned) and has a nice T.V. with an entertainment package (we used Netflix), and kept us comfortable until nightfall. It was quick and straightforward to walk to all the main sites and monuments. There also several restaurants and bars a couple of blocks away.
The apartment was clean and organised, and contained useful local information. We came by car and could park outside the door. The self-checkout arrangement worked flawlessly. I would stay there again happily. Despite the short visit, we happened to bump into Jen and had a quick fun conversation.
