Mark's flat is great - though centrally located and just off a main street, the flat itself is incredibly quiet and peaceful, light and bright, with high ceilings and generously proportioned rooms. The appliances are high-end, and it was so convenient to have a washer/dryer in the flat. The bed is comfy, and the shower fantastic - plenty of hot water and lots of pressure! Mark was easy to communicate with - very responsive and helpful. I will definitely be staying here again when I am next in Washington.
