Jason's place is a swanky rowhouse in a great location for anyone looking to be in the center of things in DC. There's a fun scene in the immediate area, with other great neighborhoods like Adams Morgan and Cardozo very close by. The metro is a 5ish minute walk form the house with a big grocery store even closer.
As an overall host, Jason went above and beyond. He provided a bike for me to use during my several month long stay; when that one had multiple problems, he replaced it with another beautiful bike that I used almost daily. He's always finding interesting things around town, and as a result I have two new jackets that I love.
Didn't have many complaints, and as a result I'll be coming back in January.
