This was the nicest Marriott I have ever stayed in. The hotel was beautiful and the service impeccable. The rooms were very quiet -- we never heard a sound from other rooms, outside, or the hallways. Beds were very comfortable. We chose the hotel to attend a graduation at American University, also on the metro red line. The location of the hotel directly across the street from the White Flint metro stop made it a conveninet location for the graduation and also to go into Washington without having to drive. I would highly recommend the hotel and will consider returning.
