Stayed there recently, on the advice of my daughter, and could not have been more impressed. Hilton spent $45Million to make this an awesome advertisement.for their brand. Efficient check-in & out, very friendly personnel, cutting edge design, spotless rooms, and no problems with parking. All of this and remarkably low rates.
Although there are a number of restaurants in the area, be certain to visit Harth, the in-house dinning room. Food, service and decor are outstanding. You will return.

We stayed at the Hilton for Thanksgiving. It was lovely. This hotel has been renovated about a year ago. We knew it from the past and it is still very nice.

The rooms are comfortable and clean and the amenities are top of the line. It may be a bit too modern in style for total ease but all in all very appealing.

We stay at the Hampton Inns as well and love their beds. This Hilton did not have the same quality beds or pillows. Therefore my mattress wasn't as comfortable.

Other than that, it was a wonderful stay. We'll stay there again whenever we're in the area.

Fairly large rooms that are very clean. I am on a special rate and get free Internet. There is plentiful free parking. The service is great. I stayed at the Marriott a few days ago and the Hilton, while a bit farther, is much nicer. The service is excellent. If you wander into a corner of the lobby there is always someone to help. Rooms are very modern and did I say clean? I didn't find one hair on the beds or towels. Impressive!

I should preface this by saying my wife and I have high standards for hotels.
This hotel had a lot going for it, but there were a few things that were just off. First, this is an old hotel... Its very obvious, but what they did with the renovations makes you forget how old the hotel is in some areas. We are gold members with hilton, and we had hoped for a room on the executive floor. We weren't upgraded, and the woman at the front desk told me it was because they don't have an executive floor. However, online it gives you the option to book a room on the executive floor. The hotel was empty and I can't imagine there weren't rooms available... All of this seemed a little shady to me.
To make up for not having an executive floor they gave us vouchers for breakfast. The breakfast was very good. Much better than most. I was not impressed with Harth outside of breakfast though. The prices were outrageous for what you got. You are better off driving over to tysons center or the galleria and eating there.
The staff was small, but they were always there when we needed them. The pool and fitness rooms were both good.
Room was decorated nicely, and bed was comfortable.
Overall for the price we paid it was worth it, but if you are looking for a luxury hotel I would look elsewhere.
