It is a cozy house with 4 bedrooms. One downstairs across from the kitchen and three upstairs. There is one bathroom upstairs and 0.5 bathroom downstairs, with a washer/dryer which you may use if you bring your detergent. The kitchen has all the necessary appliance for a short-term stay. Some are too old, though (e.g. coffee maker).
The floors are wooden and make a lot of noise, in addition to the noise from the doors. I stayed in a bedroom upstairs. Every time a guest used the bathroom I could exactly hear what they were doing there (imagine!). I had a number of friendly but loud co-guests who made my stay a bit uncomfortable. But I would not call them noisy, it was the problem with the house.
Overall, would I stay again? Yes! One of the least expensive airbnbs in DC with a nice and prompt host.
