Location on Riverwalk is excellent. Rooms were very nice, the Hilton is an old hotel, but the rooms have been refreshed making it seem much newer. Staff was very nice. Only complaint that I had is the price. One night stay with parking and breakfast for five (2 adults, 3 kids) was almost $500 with tax.

We had an excellent stay here. The bell service was prompt and curteous. The valet was expensive, but to try to park a car down by the Alamo on a weekend by one's self is impossible. Our room was clean, well furnished and comfortable. The elevators go right down to the riverwalk. Check in and check out was quick and easy. Would definitely stay here again.

Stayed 5 nights while in town for business. We had a room on the 17th floor for honor members. The room with a king size bed was as pictured on their website. It was quite large and very clean. While there was nothing special about the hotel (the decor is outdated) or the room, our stay was very comfortable (especially the bed) and service was always prompt and very polite, from check-in, to housekeeping and restaurant staff.
For the sake of convenience, we ate at all 3 restaurants on the property (Durty Nelly's, Ibiza and the sports bar). The food was good, albeit very expensive, but about the same price you'd pay at any other restaurant on the riverwalk. We also went to the Guadalajara Grill next door. The food was ok and reasonably priced. The Republic of Texas had great food, as did the County Line on the Riverwalk, but be prepared for the crowds.
The Market Square is worth the trolley ride, as is a visit to the Alamo. If you get bored, the Rivercenter Mall is across the street with plenty of stores and a movie theatre.
All in all, if you are going to be staying on the Riverwalk and you can get a decent rate, the Hilton is a great place to stay. Be warned however, parking is very expensive.

Our stay was terrific. The location was very central to everything and our room included a view of the riverwalk. Our room was clean and everything worked well. The concierge and staff were very nice ~ always willing to provide directions or input. The location cannot be beat ~ just within steps of everything.
