Marina and her family are really great hosts. Their house is a beautiful place to stay. So I had a really great time there and can highly recommend staying with Marina.

I stayed for five weeks conducting research in the Library of Congress, which is in walking distance (as well as the Capitol and many other sightseeing spots in the Capitol Hill). The neighbourhood is quiet, nice and safe. A supermarket and various restaurants are in walking distance.
The room is cosy and the bed is comfortable. Attached to the room is a study room I could use to work. I also enjoyed sitting on the back porch or in the very comfortable kitchen (which is excellent equipped by the way), talking with my hosts.

This was probably my best airbnb experience - far more than just renting a single room. I felt very welcome and surely will stay again with Marina on my next trip to Washington D.C.
