Stayed at the Courtyard in Chandler on business a couple of weeks ago. Overall it was nothing special, but didn't really have any issues.
Checkin was smooth, and I was upgraded to a King Suite. That basically gave me a separate living and bedroom area. Overall, it was clean -- although after reading some of the other postings I tried not not look too hard.
Staff was friendly. Location is great for places to eat and things to do after work. Would probably consider staying here again.
