David offers a lovely room with a lot of space and a great king size bed. His house is well located a couple hundred feet away from three bus lines that get you to/from downtown in less than 30 minutes. I also like riding bikes, and there happens to be a bikeshare rack just one block away from the house!
David's housemates are particularly nice and discreet, as well as the cat. They were really helpful and welcoming.
I recommend this place for it offers a true Washington DC experience, when you don't want to visit the city as a tourist but rather as a local rediscovering it.
