Mark was beyond the perfect host. The home had the best "housemates" offering good conversation and always had interesting stories. While there was always someone around, no one was ever intrusive. I had no problems going to sleep at night or escaping to the quiet of my room. The house has brand new AC units in the rooms and main dining areas that keep it as cool as you want (literally you could freeze yourself if you wanted to) - something that is rare in DC. The location of the home is fantastic - close to the metro, museums, and Trader Joe's. While not an updated luxury rowhouse, this home is historic and offers plenty of charm. I could not recommend it more highly, and I was sad to leave after 6 weeks.
