Mark's apartment was fantastic! My husband and I traveled with our 1 year old for a touristy trip to DC and found the location very good (5 min walk from the Nat. Portrait Gallery, 15 min from the mall, 5 min walk to a Walgreens, and surrounded by restaurants and window shopping), and the apartment to be incredibly spacious. 2 large carpeted bedrooms each with large closets and bathrooms. The space feels new and clean, and the sheets felt nice. It's located within a fancy apartment building, with luxury shopping on the ground floor. There is visitor parking in the basement of the building, which we thought was super reasonable (even cheap?) for a big city (something like $25 for 24h?). Mark was a kind and attentive host, responsive, and flexible. We would definitely stay again.
