My wife and I stayed here for one night prior to catching a flight at Dulles. Welcome at the front desk was pleasant and we were upgraded (as Diamonds) to a top floor, very large room facing west towards the highway. The view was actually quite nice and the room was huge, modern, and well furnished. We stayed on a Saturday night so the room rate was quite inexpensive.
We used the executive lounge for snacks that evening and it was quite well stocked with a few hot snacks and the usual cold items. We had dinner at the restaurant, just adjacent to the bar. The meal was quite nice and reasonably priced.
I used the fitness center that evening: typical items, a few in less than good repair, but overall a decent experience.
Overall, I was very pleased with the stay. Shuttle to and from the airport was efficient and easy to deal with.
