I’ve used them since November of 2022. They have been wonderful, kind, friendly, and helpful. Units are clean and grounds are well kept. I moved out and then needed to move back in within a week. They got me back in and worked on the price for me as well. The price has gone up twice since using them but I guess that’s normal. My experience has been great.“

Absolutely recommend Attic Storage on 20! The owners are incredibly kind and welcoming, such nice people. Move-in was smooth and hassle-free, with easy drive-up access and plenty of space to maneuver around the property. The units are super clean and well-maintained, and everything about the process was straightforward and stress-free. Great experience from start to finish!“
