This is my new favorite AirBnB in DC. It's an amazing deal for anyone who's doing business on the Hill or with the federal agencies. It's literally across the street from the Potomac Ave. Metro (Blue-Orange-Silver lines), two stops from the House office buildings, four stops from L'Enfant Plaza, and seven from Metro Center.
The apartment is clean and tidy, which you don't always find in AirBnBs. Everything works and the mattress was adequate. There's a grocery store on the ground floor of the apartment building and a quirky Mexican restaurant across the street. The host is nice and responsive and she has cool friends.
