We stayed here for three days while visiting Washington on my daughter's spring break. I would say the place is as advertised. It is small but comfortable for up to maybe 3-4 people. It was in great shape. It was very close to the zoo for walking and close to a metro stop for going see the sights. We were able to arrange for parking in the back which worked out well. Parking would be a big issue if not for the spot available. Overall, this turned out to be a nice place for what we wanted to do and the host was very responsive.
There were only a couple of minor things that should probably be mentioned. First, the building has steam heat which works well, but the radiators do make some banging noises at night when the steam circulates. The radiator in the bedroom did not seem to have a knob for controlling the heat. Second, it's a big old building with wooden floors so you can hear people stomping around upstairs sometimes. Not a huge issue. Overall, this is a great spot.
