Are rental car reviews always so low because people only review when they've had a bad experience? I rent cars pretty frequently, and really have no horror stories to tell. Sure, they try to upsell you on the larger cars (not to mention that damn insurance), but oh well.
The staff at this location were efficient and very friendly - got me through the process quickly, and offered me a map (and verbal directions) to get myself around Phoenix. The car was clean and ran well. No complaints.
