Washington Dulles Airport Marriott
Clean room (although I found it to be quite small, especially the bathroom). Staff was very pleasant. We had dinner in the dining room and it was delicious.

Everything about this hotel was AWESOME! The proximity to airport, you can see the landing stip from my room. The rates are incredible as well. Rooms are immaculately clean & spacious. Will stay there every time we fly out of Dulles.
