I usually stay at the Hyatt in Reston but as it was full I stayed here. The westin hotel is gorgeous. The beds are huge even in the basic room and they are the comfiest beds ever. Service was great other than a very abrupt lady in the restaurant at breakfast who didn't seem to want to be there. The reception staff were very helpful explaining the shuttle bus into Reston (it's free) and to and from Dulles (also free and very regular). Truly the only downside is the distance to Reston town centre but if you have a car or you aren't needing to be in town then there's no problem here at all.
