Great staff! They were always very helpful and attentive to our needs. Only downside for us was that the room was a bit too small and tv would act up. Otherwise the place was great!
The front desk staff was pleasant and welcoming. The room was clean but a little smaller than other AC hotel rooms I have stayed in. No complaints. The elevators were also very fast with never any wait time.

Checked in on 12/19/25 and the young gentleman that assisted us was super friendly and extremely helpful. Definitely going to stay here on our next San Antonio trip.
Rooms are very clean. Staff is helpful and incredibly friendly and pleasant to talk to. I didn’t want to leave. I’d stay here again next time I’m in San Antonio and recommend it to everyone who visits.
