Rooms aren't convenient
The location of Hyatt Place Riverwalk is ideal--within walking distance of restaurants and tourist sites but away from the crowded section of the Riverwalk. The staff is great--friendly, helpful and always "on call". The free breakfast is typical hotel breakfast--McDonald's with silverware.
Our room was clean and had a nice view of the riverwalk. However, whoever designed the room should have to spend two or three nights there. The sitting area and kitchenette area are too large, the bathroom and closet are too small. One literally has to wedge oneself between the toilet bowl and the shower stall to close the bathroom door. The closet is right next to the wash basin, so if one person needs to get clothing, and the other is washing her face--collision!
The air conditioner was loud, but at least it worked well. 
We enjoyed our visit to San Antonio, and were very pleased with the free parking, staff, and location of the hotel. The rooms left so much to be desired that we will probably not return on subsequent visits.
