Read some helpful reviews of StorageMart, shared by real renters with genuine experiences and honest opinions.

I got a storage unit in October and have been very happy with the unit and the local staff. I assumed that there would be a price increase at some point but didn't expect one in 3 months and I didn't expect it to be about 30 percent. Keep this in mind when you're looking for storage alternatives. I'll be looking for a new storage company. ... Read more

Reserved my self storage unit today with Liz. A great experience in person, and Liz could not have been any more helpful and knowledgeable about the whole process. She made this process easy, and I left with ease of mind about using CubeSmart. Thanks Liz! ... Read more

I researched several local storage facilities, including calling locations and asking detailed questions. I was blown away by the professionalism, knowledge and overall kindness of both Keith and Melissa. They are a powerful team who understand customer service. And wow! I've never seen such a clean storage facility. I looked at their outdoor units (no AC), but ultimately chose an indoor unit with AC. Both are great options but being indoors means you don't have to worry about rain, snow, or heat - definite perk. I highly recommend this place and would use it again if ever needed. ... Read more

Very disappointed with the way customers are treated and talked to. What’s good for the customers, employees can do whatever they want. As a moving company, please use ANYONE else for your storage needs. We offer discounts if you cancel with this company. That’s how disappointing this place is. ... Read more
