Dennis and his wife were excellent hosts. I stayed for ten weeks and I cannot remember ever having to bother them about anything that did not work or that needed to be changed etc.
The neighbourhood is nice and just a 15 minute walk either to Waterfront Metro to the west or Navy Yard Metro to the east. Navy Yard offers countless good restaurants and bars to go out, however Metro Centre/Chinatown is just two stops away.
All in all the room was as described and Dennis was a great host.
