FREE Stainless Steel Disk Lock with new rental


Easy to use, competitive rates and friendly and professional staff.

Very friendly and helpful (above and beyond) staff/owners. Stored stuff there for a year, and it was in excellent shape when we retrieved it.

Very friendly helpful people. Appreciated the free water every time I needed it. I stored in Ace for 2 years and nothing was every wet or damaged in any way. My unit was secure and I felt happy to keep my extra belongings there.

I rented two units for a year and 1/2. They managed to get me two right next to each other. They were friendly and available whenever I needed anything. I had easy access to my stuff and it was not damaged at all in the 2013 flood. The unit was clean. When I moved out of the first unit they credited the partial month payment to my other unit. I didn't have to give a month's notice to move out. They were GREAT.

All was easy and quick! No issues, great space. Love that Uhaul is right across the street because that saved on mileage for moving costs.
