We arrived to the location and there was no employees around. Called the numbers posted and no response for over 4 hours. We were forced to find another location

A bit of a hassle checking one there and phone number had full in box. Finally got in touch with someone who had to hunt down the owner`s wife ? But she was very accomodating. Clean and safe.

When I got to Flagstaff I phoned them and was told that they didn`t have a space available that would fit my stuff. I went to a different storage company that had space.

The storage facility is actually approximately 9 miles south of the center of Flagstaff, something not clear from U-Haul`s reservation system, making it impractical for my specific needs.



Mountainaire had no record of my reservation and referred me to another facility with professionalism and friendly service.



Gate entry padlocked vs.key card there is no on-site office or attendant however, the price was less than the competition, the owner was accommodating friendly, there`s 24-hr access.
