I had originally booked on line so when I showed up for unit the man in charge took excellent care of me and my possessions . He made sure the location of my unit was safe and free from any type of flooding .. He was very professional and went that extra length to make me feel safe .


Great place to store your stuff!

We reserved a storage unit online for our move to Key West but when we got there with all our stuff we found out we had miscalculated and needed a much bigger unit. Danielle (spelling?) was very helpful! She met us at the StorageMart and upgraded us to a bigger unit at a fair price that had easy access for our 16' moving truck so we could just slide everything right down the ramp. That helped a lot as it was only my husband and I and we were exhausted from driving for 8 hours straight! Would use StorageMart again anytime! Thank you for great customer service!


Totally accommodating experience!

The rental experience was very positive. The staff was polite, kind and helpful. I needed to get to the unit immediately and one of them met me there to unlock it (satellite site so no office on premises). I left my license at the rental office and one of the staff brought it to my storage unit. I bought boxes and got 20% off from the online coupon. I also had 99% off first month rent. My space is in a climate controlled unit, so it was cool and clean. In an otherwise stressful moving situation, Storage Mart was a positive experience.

I contacted our local office on Stock Island in a pinch due to a change in local parking laws and they could not have been easier or more amicable to deal with! Thanks to the staff there!
