Phoenix area boarding/kennel recommendations?

Hi - I have a good friend who is a loving and concerned dog parent looking for recommendations on boarding a nearly 1 year old, medium sized mixed breed dog while she is out of town.  She had an appointment to see one place booked in advance that looked so promising only to show up and have to call the owners (supposedly on site at all times) on their cell to find they were "away".  Not pleased. 

If anyone has recommendations, please let me know.  PM me if you don't want to "advertise" a particular business, but any first or second hand knowledge appreciated.  They live in Queen Creek/East Valley area, but would be open to other Phoenix area locations.  Just looking for somewhere they can feel confident in.

 Thanks - Lisa
