The apartment is located in a very nice neighborhood, near restaurants, shops and metro stations. It's large enough for 4 people.
The furniture is a bit worn out, and the decoration needs refreshing. Overall it's quiet, but we sometimes heard noisy neighbors (not sure whether from upstairs or the next house).
Ed was quite responsive to our requests, except for helping us find a solution with our luggage on the last day.
Overall it's a OK rental, especially if you spend most the day sightseeing in Washington D.C.
