I really enjoyed my stay with Christopher and Marina: they are very welcoming and made me feel at home right away. I stayed with them for almost four months while doing research at the Library of Congress, and I was always happy to go home at the end of the day. I cook my own meals most of the time (rather than go out), and it was pleasant and easy to share the kitchen.
I loved the neighborhood, which is gorgeous in the springtime. Everything I needed was in convenient walking distance: groceries, metro, Library, also the National Mall.
A great choice for anyone looking for good company and a homey place to stay.
