If you are looking for a room that is reasonably priced Bill's place is a great option.
I stayed at their place for three months for a summer internship. The room is very nice and properly furnished. The bed is comfortable.
I had all the amenities I needed such as laundry, kitchen access, and wifi.
Bill and his wife were great hosts and I am thoroughly pleased with my stay there. If I am going to DC I would happily stay here again.
