This is a great place to stay in DC due to is very accesible even if you want to go for a running around the main landmarks. The neighborhood is beautiful and quiet and the apartment is very well equipped with what you should need. The only downside is that the AC could be a little bit loud for people who are sensitive to sounds at night.
Barry is very attentive and you will find a very detailed guide to use the apartment as well as recommendations to explore the neighborhood and the city.
