The stay at Dans apartment was perfect and there is nothing to complain about. The apartment was as described and also clean. You are in Downtown (Union Station) in 20 minutes with the free DC streetcar.
Dan as a host was great. He offers help and sightseeing tips and we never waited longer than 10 minutes for an answer. Check-In and checkout works easy with a code key without problems. We had a nice stay in DC and that is based on the very good Airbnb we found!
