The two great things about this listing are the cleanliness of the room (and its amenities) and the responsiveness of Mary. The reviews I read about the place influenced my decision in choosing the listing - true enough, the place was clean, spacious, quiet and comfortable. Likewise, Mary was a very considerate hostess - very responsive to requests but at the same time, ensured and respected the "landlord/tenant" privacy relationship. The place is conveniently accessible to and from Union Station and the tourist attractions of the city. I definitely will consider staying in this place again when I go back to Washington, DC.
