The apartment was exactly as described and as it looks in the pictures. It was exceptionally clean and the host provided thoughtful amenities one wouldn't expect - like a first aid kit - which we ended up needing!
We weren't able to meet them due to scheduling conflicts, but it was very homey, quiet, neighborhood was safe and convenient for public transportation and good local restaurants. We didn't spend much time actually in the apartment, but it was a great place to come home to every night after experiencing everything DC has to offer.
