Stayed here 2 nights while touring Virginia Tech. It's four minutes from the VT Visitor's Center. The Hilton gives a AAA discount, has good complimentary coffee in the lobby at all hours. Rooms were clean, bathrooms are roomy, HBO on the tube, and a generously sized desk in the room. Climate control is easy to work and effective. All common areas are nicely decorated, and there is a small business center that your room key will open, with two computers and printers.
Don't be concerned about the very firm mattresses; they have a dial on the side near the head of the bed that releases pressure in the mattress. We turned ours all the way to "soft" and slept just fine. I'd rather have a firm mattress than a back-breaking soft one anyway! Breakfast wasn't included, but there were lots of options at the buffet, for $8.95 a person. Staff very polite and helpful.
