This storage facility has excellent customer service and they will do their best to handle any concerns or problelms you may have. The only thing that i wish were different is i wish "CubeSmart" would allow me to have two credit card numbers linked to my account. They said they will auction off my storage unit contents if my account is not paid for 44 days. i often travel overseas for many months at a time, and sometimes my primary credit card account may be put on hold for whatever reason. i would like to have a secondary credit card number on my account, so that if my primary credit card doesn't work for any reason, my storage unit will be charged to the second credit card that i provide. my life's belongings and everything materially important to me is in that storage unit. i cannot risk losing the contents. this is a big concern to me. but otherwise, i am very happy with "CubeSmart."

I recently had to downsize my storage unit. The manager and staff were fully cooperative and facilitated the shift. Part of it involved using on site rental truck for $10 to move some of the contents to my home. What a deal!!

This place is great! My family is currently moving storage from one unit to another; Martha, Roland, and Natalie have been extremely accommodating, which has made the stressful process much easier.

The staff is very friendly. The pricing was good compared to other places. I have had various storage units throughout the years and have been very pleased here. Highly recommend.

Called around to all the storage facilities in the Diamond Bar area, Cubesmart was definitely the smart choice. While competitive in cost with the other storage companies the customer service is what sold us! Natalie was friendly, informative and accommodating. Highly recommended this facility for long or short term needs!!!

Cube smart was the easiest storage experience I have ever encountered. I used it for a couple months, and it was very clean and easy start up. I walked in and the man at the counter got me set up in less than 10 minutes, while still helping out three other customers at the same time. I purchased a lock from them as well which was convenient. After a couple of months, I found a new home and had to move! I came on a sunday at 3:05, right after after their office was closing. The woman at the office Martha instructed me that since already closed down the office that she would close my account the next morning if I were to clean out my storage that day. I cleaned it out, and she called me the next day telling me she closed out the account, and I was so happy and pleased because most people don't follow up, and she went above and beyond even though I came to the office after hours. I would always recommend cube smart, and I'm really happy with my experience. Thanks Martha! Ali

I used the storage for about 8 months, and this is the best storage I've used by far. They have a service that renters can avail of and that is a free use of a small truck. That was so convenient and helpful. The facility surroundings were always clean and the staff all professional and helpful all the time. Will definitely recommend to my friends. Thanks Cube Smart for a wonderful experience.
