Almost 5 stars, definitely more than 4
I was here with my husband who was attending a weeklong conference. We received a warm welcome when we arrived, the check-in process was very smooth and our porter was friendly & informative. We were given a corner room(handicapped room) on the 19th floor with a king bed and lots of floor space. The room was very quiet because it was facing southeast - No view of the Riverwalk which neither of us missed. Instead we could see the Alamo Dome and the Grand Hyatt. The bathroom was quite large with a walk in shower and good lighting. There were only 2 hooks for the towels. It would have been nice to have a towel rack plus a towel ring near the sink since our room had the cards requesting that we help save the environment by reusing the towels. I do support this but also want my towels to dry. Our bathroom did have the wall space to add those items 
The room itself had a flat screen TV, a coffee pot, hair dryer, safe and computer hookup. The hotel had a hot tub and a large indoor/ outdoor pool. There was a bar by the pool which was closed the afternoon that I swam. The pool was especially nice with lots of lounge chairs available. Other amenities included a fitness room, concierge services, a Starbucks in the lobby and 2 computers for airline check-in & to print boarding passes. I do not know why but the temperature in the lobby was always a bit too cold. The hotel's location is on the Riverwalk and is very convenient to the River Mall. Denny's was just across the street (good for breakfast). Also the Alamo is only a few blocks away and Hemisfair Park is about a 10 min. walk. 
Parking was expensive at $25/ day for self parking. In addition a $2.03 parking tax was charged each day! We were also charged $14 / day for the internet. At other conferences, one or both of these items is usually discounted or not charged. Those additional fees do add up. We later discovered there was cheaper parking clsoe by.
