Hotel Fine, Not close to Riverwalk!
Stayed at Crowne Plaza San Antonio Riverwalk for three days, early October, for conference. Check in fast and friendly - bellman/valet took luggage to desk quickly and everyone very friendly.
I am a Priority Club member and was "upgraded" to the Executive Level. Had colleague on lower floor who's room was identical, so the only difference in Executive level was waiting on elevator longer. The elevators were horrible for the entire week - this is a fixable issue that seems to have been a topic on previous reviews of property and should be addressed!
Room was clean and had usual amenities - tv, couch, desk, chair. No refrigerator or microwave although a refrigerator is available for a one-time $25 charge. Toiletries were Renu - Crowne Plaza branded and pleasant, non-floral scent. Shampoo, conditioner, lotion and bar soap - no shower gel but ok. Towels were soft and fluffy. Not huge but not skimpy. Coffee pot was small, 4 cup and only one pack of caffenated and one pack of de-caf furnished. Easy to bring own coffee and filter and use. Ceramic coffee cups nice touch - no paper coffee cups is good.
Bedding was great - total of 6 pillows, counting ones in closet. Mattress a bit too soft for me but ok. Plenty of plugs in room, including plugs in lamps so you don't have to crawl on floor for plug-ins by desk. Our group rate included free internet, which was very slow. I brought my own mi-fi hot spot and it worked fine.
Restaturant was good - group 25% discount made prices reasonable. Only one beer - a domestic - on tap - and a bit disappointed that no Mexican beers available, considering location.
Perfect segue - location. Cab rides were cheap, thank goodness - this hotel is not close to the "good" part of riverwalk - at least not for someone with mobility issues. Walgreen's about 4 blocks away - don't advise going there alone or after dark. Homeless/jobless hanging out on corners, muttering observations in both Spanish and English. (Have to say they were creative - I'd never thought about doing something like "that"!)
Conference rooms were good but long walk to Fiesta Pavilion where we met for most sessions. Housekeeping did a great job in both rooms and conference area restrooms. 
Check out was fast and accurate. Bill was correct. Bellman held luggage until mid-day departure and had cap to airport waiting for us early. 
I'd stay here again, if visiting San Antonio. The main complaint I have that is fixable is the elevator.
