Supreme's place is really perferct for a stay in Washington D.C. We stayed there for 3 nights with a company of five. There was plenty of room and we were very happy with the fact that we could park our car in Supreme's garage.
The apartment has everything you might need. Even a computer with printer. Unfortunately, we didn't meet our host in person but Supreme kept in touch via messages. Communication with him was very easy and we think he takes great care of his guests.
