This townhouse is located literally two short blocks from Nationals Park, and is the perfect location for catching a game. Dennis was a great and responsive host, even making some allowances that included adding an inflatable mattress for an extra child and being very flexible with check-in times. The place was clean and orderly, and Dennis even provided towels. He also had a guest parking pass waiting for us, which we could use to keep our vehicle on the street outside.
There are three individual rooms on the second floor, and one shared full bath for all three rooms. This works, if everyone is considerate.
The only potential concern might be community safety, as the townhouse is in a neighborhood where I would not feel safe walking around much at night. (Coming back from a game at 10pm was fine.) I might stay somewhere else if my goal was to stay in DC awhile and see sites other than Nats Park. Again, though, for a ball game, it was a great stay.
