Average, but what else you want on the business trip?
I have been for Hilton hotels for now 2 years for my business and pleasure trips. 
Well, this property is little old but is OK/avg for the one night business trip in my opinion. Hotel service staff is good, responsive, gym is good too. They have nice restaurant if you want to relax after a long day, there is a pool. Bed is not that comfor
I like them specially as they have shuttles to my workplace in phoenix. 
All in all a good place, one suggestion, why dont you give a bottle of water complimentary in summer to your guests as your other member hotels do ?
