This home is in a PERFECT location. Right around the corner from the Metro station, a short walk to the Capitol building and Library of Congress. With kids we took the Metro to the middle of the National Mall but very doable walk from the home. The home itself is beautiful and very comfortable. It was stocked with coffee, tea, some snacks and 4 Metro cards. I highly recommend this stay for anyone who doesn't mind climbing some stairs.
The bed in the bedroom was very comfortable. The sofa sleeper was exactly as you would expect. There was a little more noise throughout the night than we are used to but we enjoyed the heck out of every second!
