The stay in D.C. was really nice. It is a bit of a walk to the city centre, but it is still okay to walk the distance. Also there are multiple bike rentals nearby, if it has to be faster.
The neighborhood is lovely, so there is not much need for going far away (except for Sightseeing of course). There was even a map prepared for us, that explained the neighborhood, with some recommended places nearby. All in all a place to recommend.
