We liked Diana's place. The location is great. It is about 15 min walk to the Congress
building - the location is just behind it. We would often walk in the morning to the National Mall and back. A metro station (Eastern Market) is a few minutes walk,
and it is a reasonably quick ride to most central locations.
The apartment itself is comfortable for 2 people. It is in a semi-basement, the windows are above the ground. It has everything we needed. We had a car, and Diana gave a guest parking permit for street parking in front of the apartment, which was very convenient. Communications with Diana were always easy - she replies very quickly. A good place for spending several days in D.C.
