My wife and I stayed here for a large family function that took place in one of the hotel ballrooms. We found the hotel to be well kept and clean, and the staff were helpful and friendly. This hotel is popular for wedding receptions and business meetings, and there can be a lot of traffic in the halls at night. The rooms were standard for a business hotel, a bit on the small side, but nicely furnished. The breakfast was another high point, with a large buffet with many hot choices, an omelet station with several cooks to make the line go fast, and a great selection of fruit, yogurt, and pastries.
I don't know if I will ever need to stay in Virginia again near Dulles Airport, but Westfields Marriott will be one of my top choices. Airport access is very easy.
