I can't imagine the pressure this staff is under... this hotel is literally walking distance to Hilton's new (2009) world headquarters.
I would ABSOLUTELY stay here again. The staff was efficient at every touch point, check-in, room service, check-out. Greeting from the staff I encountered in the halls. The room was spacious, clean, and that modern decor that wasn't "neo-modern." Loved the shower. The lobby wasn't as happening as say the W in Chicago, but well utilized. They had a spacious business center. I am not much one to eat alone in a restaurant, so I didn't try that, but the room service came quickly and was tasty.
This is really close to the Tysons Galleria mall. I hear it is an awesome mall, but really didn't have anything for me to cause me to walk over to it.
