We usually try to stay at the Residence Inn Dulles Airport at 28 Centre when I come into town. My partner is a Flight Attendant for a major airline and is based in DC. This hotel is like home away from home for the both of us. We really like the newly remodeled deco (red is so in right now). The kitchens are well-equiped with everything you would need, and the hotel staff is very friendly and helpful (especially Matt). Just a great hotel.
