Fantastic staff, decent accommodations.
I stayed at the St. Anthony for a wedding, and I'd be remiss not to give the staff their due. EVERYONE, from valets to the front desk to housekeeping to bartenders to servers were completely on their game and exceptionally friendly. Not only were we always greeted with a smile, but the greetings always felt genuine.
The facilities themselves were okay. I'd give the St. Anthony five stars for charm, especially in the lobby and common areas, but but probably three or less for the upkeep of the rooms themselves. I suspect may travelers may consider old world charm a quaint selling when it comes to decor but not when it comes to the functionality of the bathrooms, etc. Our room was quaint, but the bathroom could use some updates. The old plumbing and wiring were just, well, old. The hair dryer repeatedly tripped the breaker, and the sink had little water pressure (the shower not bad, surprisingly). Plus, towel racks were missing. The bathrooms were just a little run down. Not dingy or anything, just in need of a little TLC.
Those nits aside, I'd stay there again. It's priced fairly. The bed was very comfortable. It's a short walk from just about all the sights in downtown San Antonio. The ambiance is nice, and the staff more than compensated for the very few gripes I found with the place.
