The Team in Diamond Bar were very helpful. They called me after I made my reservation online, worked with me when I needed to move my unit to a larger space. Helpful and courteous. I would recommend this facility to family and friends.

Password Retrieval
4 /5
September 27, 2013
Like the storage facility, esp the hours. I needed into my online account and my password did not work so went thru the retrieval process. I was sent an email which had four different passwords. None worked. I finally found another email with four more passwords, and the fourth one worked. Suggest you look into that procedure; pretty frustrating for the customer.
