Lovely basement apartment in DC. Not too far from all the places you want to see. Safe, walkable neighborhood. I really have come to prefer AirBnB to standard hotels. Helps get us off the typical tourist path and see and explore parts of the city we might not ordinarily find.
The apartment was sparkling clean and all the linens and fixtures etc were high quality. Lots of extra amenities from a basket of throw blankets to toothpaste, shampoo and creamer for coffee that made it feel like you're staying at a friend's house.
