I stayed at the Residence Inn in Mesa, AZ during the 2nd week of November 2013 and experienced an enjoyable stay. Upon arriving, the room was clean and pleasant. However, housekeeping missed servicing our room the next day. (Upon complaining, we were offered a Marriott gift card for future use.)
There's a better than continental breakfast offered gratis every morning. Unfortunately, very few fresh fruits were offered. I didn't get to use the pool or fitness center during my stay, but they're also available and appeared pretty basic. 2 computers with a printer were available for free use and the rooms have free Wi-Fi.
