We stayed at this b&b for a weekend i Washington. It was an excellent choice (and I have stayed in b&bs many times before, so I have some experience). Keith is a great host, the house is beautiful (we had the Terrace Room), and the location is very convenient - about 15-20min walk from major attractions (White House, National Galleries of Art, Smithonians), and about 5 min or less from a metro station. There is a grocery store around the corner.
I would absolutely stay here again and recommend it to everyone!
