Mark was a welcoming and congenial host. I stayed for 2 months while working in DC and had a lovely stay. The house is charming and comfortable, with a feeling of community that Mark offers his guests. My room was spacious, with big windows, lots of light, closet space, desk -- everything I needed to be both comfortable and productive during my stay. The location is wonderful for walking access to DuPont Circle, Adams Morgan, U Street Corridor, 14th Street -- any direction you go you'll find restaurants, conveniences and interesting neighborhoods. Its about an 8 minute walk to DuPont Circle Metro and about 10-12 minutes to U Street Metro. I'd recommend Mark's home without hesitation and hope to have the chance to stay there again when I'm in next in DC.
