We stayed at the place for two weeks, and the time went really quickly. For the three of us (two adults and one 8 year old) the size of the rooms worked out well. It's a large house, shared by the owners, tenants, and airbnb. The place is nicely decorated and well maintained. The rooms are on the second floor, next to the owner's rooms. There isn't a separate entry to the airbnb part. The only issue we had was with the shower. The stand-alone bathtub doesn't have walls around so it's easy for water to spill on the floor and leak downstairs.
The location of the place is really convenient. It's located less than 5 minutes walk from the metro and about 20 minutes by metro from the Union station and gallery place. We wanted to enjoy the cherry blossom festivities in downtown D.C., and it was very convenient to get there using public transport.
