1st class facility located at the corner of 2 major streets. A1A and Hwy 312. Climate control or not. Some buildings are outside of the 3 floor facility and customers can park right in front of their unit. And another huge 1 story building,also separate, is Climate controlled. Awesome staff completes their perfection. And, NO, I am not kin to anyone there not had I ever met any of them prior to finding it on my own. Lucky me.Kay Ingram

Clean, easily accessible outdoor units with indoor climate controlled spaces also available. Reasonable rates and friendly proactive employees. I appreciated the spacious complex, which made navigating a 26' box truck right up to my locker a snap, rather than a chore.Luke Jette

I have been renting from Atlantic Self Storage for a while now. I have started with one unit...moved to another...needed to set up auto-pay. Point is, whenever I needed something or had a question or wanted to make a change, they were always available to help. The staff, Dawn and Rob, are wonderful. They are always, courteous and professional. They are always willing to help in any way they can. The building is always spotless and the units are clean and in perfect condition. Just wanted to say "thank you" for making a stressful task just a little less stressful. You guys always seem to be able to put a smile on my face!Kelli Palmer
