Not fancy, but clean, quiet, and the breakfasts were great!
We stayed at the facility while attending the United States Grand Prix (near Austin). It was a bit of a drive each day to and from the facility, but we weren't willing to pay $150 or more to be closer. 
The motel was, well, basic but clean. We all slept well. The beds were comfortable. Everything worked. it was great having the refridge and microwave, which we used daily. 
The breakfasts were particularly helpful for us. The staff had the simple breakfast area prepared every morning at 6 am, and that's when we were there! It helped that we could just grab and go, and be on our way.
Next year, we're going to stay at a motel closer to Austin, but if I did need to be in San Antonio, and needed a basic motel, I would stay at this facility again.
