I'm a first time airbnb user and I was a littler leery and nervous when booking. When we first arrived an elderly woman showed us to our room and gave us the keys and towels for the bathroom. We immediately took a nap on the wonderful memory foam mattress.
The next day we headed out to DC the metro station is maybe a 10 minute or so walk either the Waterfront station or the Navy Yard/Ballpark station. When the Nationals are playing you are within a block of the game. The house is located in what seems to be a combination of a new rising neighborhood and a rougher part of town. However we walked around and back home after dark and were perfectly fine. Overall this was great we had the place to ourself and his TV has Internet built in which was great.
