First used them 14 years ago when I moved out of my condo, I'm using them now again for my house renovation and they are just as good and friendly now as they were 14 years ago.

Good and reasonable price to hold items. I left my items here for 2 months and had no complaints. Conveniently next to the freeway too.

I really enjoy working with CubeSmart. They are very helpful and friendly. Dalia was a delight. Roland also helped me in the past as well.
