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.

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 JetteOrganized managers with great follow up
Clint RichardsonGreat staff, very accommodating, clean, and safe. Exceeds expectations.

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!

This is an excellent location on the island. They just opened a new indoor climate controlled two-story building that looks amazing! Outside units are well-maintained and the staff that runs the facility has been amazing for the last two years. Even during the construction access to our unit was never an issue. The gates are currently not closed due to the finishing of construction but anticipate they will be again shortly. When the gates are closed there 24 hour access is super easy. Our biggest concern about this location was flooding due to its close proximity to the ocean. We have weathered to hurricanes and not a drop of water has entered our outside unit. We are very pleased with the facility in management team. Prior to construction the back portion of the property had vehicle storage. I'm not sure if that will be offered once construction is completed.

We've had 2 storage units at Atlantic Self Storage on the corner of A1A and SR 213 for 3 months. After a long and stressful move from Kansas City to FL, we were not looking forward to the whole process of having to find storage space. Janet and Steve have been absolutely fantastic! They are so kind, understanding, helpful, and friendly...both as we checked in and as we were checking out. We have had nothing but excellent customer service from them. They even contacted us while we were in Belize to tell us that the lock on one of the units was locked, but not through the loop of the door, which allowed the door to be opened without a key. We were able to make arrangements for a friend to go in and fix it, and of course all of our belongings were unharmed. We highly recommend them and would use them again, if we ever have the need. Thanks, Janet and Steve, for keeping great customer service alive and well! Ann & Ted
