John is probably the most generous host you'll meet through Air BnB. His apartment in Dupont Circle is centrally located and just a short distance from the metro. He was very flexible on check-in and check-out time which is important because you would not be accommodated so easily at a hotel. The outdoor patio area is a great bonus if you're visiting during the warmer DC months. The apartment is very clean and has all the amenities you could hope for. I would definitely recommend!
