This is one of the best Marriotts that I have ever stayed in. I'm a platinum member who has stayed in a lot of different Residence Inns and this one is top notch. The staff was friendly and the hotel was very clean. The lobby was awesome and it even had a game room for the kids to play pool and Wii games. The breakfast and the managers reception were excellent. One of the best I've ever seen at a residence inn. There was a lot of variety of food and I was very happy. The staff was very accommodating and took care of my family's every need. When in the Dulles or DC area I would definitely recommend staying here.
