Testimonials


We are always working to assure that our customers are happy!

Cottonwood Self Storage was such a life saver. I was in a really bad bind and had all my belongings in my car. I began to call around and they answered the phone even though it was after they had closed. I was so fortunate to have found Cottonwood. They are so friendly and so super helpful. They went above and beyond in helping me figure out my storage needs. I can't thank him enough or even describe how much his extra level of service truly made a difference to me and my life. Great place, good location and excellent service. B Lee
I called in a pinch from across the country, and Cottonwood was extremely helpful & accommodating. I've had my unit for over a year, with no complaints. Finally moving out & giving up my unit, and I highly recommend to anyone who is looking. Friendly, responsive staff, clean units, safe & secure location. Awesome!Jennifer Dimiceli
From the moment I made my first phone call to the moment I moved out of my unit I couldn't be happier. Cottonwood Self Storage has excellent customer service. Paying my bill each month was a joy because they made it easy to pay. You can pay online, by phone, or take payment into the office. I enjoyed paying by phone each month because they were very polite and cheerful every time we spoke. After paying my bill I received my receipt by email right away. The unit I had was a 10x10. The unit had plenty of lighting on the outside and a gate which made me feel comfortable knowing my possessions were safe. I did not have any issues during my 8 months rent. The price was very affordable and they never once raised it on me. The location and price was wonderful and the staff was amazing to work with!!!Katie Robertson
