We visited Washington as tourists with family, and this house exceeded our expectations. It's an impressive historic 3-story townhouse close to Capitol.
Location was perfect! The neighbourhood is quiet, and close to everything. We liked that we could get around everywhere by walking, and still we were away form the city noise.
Space: it's nicely decorated and spacious. There is common space, as well as 3 bedrooms for personal space. It gives you a homely feel, I personally liked the books collection on the 2nd floor :). Highly recommended.
