My wife and I stayed at David's place with another couple while exploring DC for a couple of days. This place is just as advertised, spacious and clean. It is also perfectly located just a few minutes bike ride to the Capitol and the monuments.
David was very responsive and made our stay comfortable and enjoyable. I would place David's place in the top tier of airbnb properties as it surpassed our expectations. I would definitely recommend this place and would not hesitate to stay here again.
