Kerry is a super host - very friendly, very helpful, extremely welcoming. I felt very much at home. She went out of her way to ensure that there would be foods I liked in the kitchen, and allowed me to have full use of the kitchen and dining room for cooking any meal I wished. I really appreciated this. She helped me to arrange transport from/to the airport and generally was available and welcoming in all ways, while also respecting the privacy of the third floor guest suite (the host is resident and uses the first and second floors).
The guest suite has a pull-out sofa double bed (not tested), a very comfortable single bed, a great shower, and includes a comfortable living space full of books, movies, etc...
I will stay again when I return to DC.
