Need to repair door. Does not close properly,

I let the front office know about door not closing properly and they didn’t take the time to confirm my issue with the door. I am not confident my items will be safe. They did tell me they will call and have a maintenance person go see, but could not tell me when.

I love working with CubeSmart Self storage!

As a college who goes home for the summer every year, I always look for a place to store away my school things. For two summers now I have been using CubeSmart self storage as I absolutely love working with them! From their great prices to amazing customer service every time I could not think of going anywhere else. I will definitely continue to use CubeSmart and hope that others will too! Thank you CubeSmart for everything!

Recommended: Yes

David May 27, 2014

When I arrived to move in my appliances I had movers with me who we're being paid hourly. They required an additional hour of time because the security gate was inaccessible to my new entry code and there was no one on the office. I had to go to the new apartment and have my movers take the storage appliances out of the front of the van to get to the apartment furniture, then reload the appliances and travel back to the storage facility. Not a good experience.

Recommended: No

Recommended: Yes

Kathy Jul 24, 2012

The space I booked thru Sparefoot was not the space that was reserved for me at CubeSmart. No one had explained to me prior to my reservation date that the 5'x10' space I reserved is actually TWO 5'x5' space next to each other. There was no other fine print in the reservation stating that fact, which is very misleading. I did not find out that was the case until I arrived at Cubesmart to fill out the paperwork, leaving me with no choice but to select another unit that fits my needs.

Recommended: Yes

Olga McR Jun 23, 2012
