Our Customers Say...

We recently moved to East Wenatchee and found the staff to be incredible: friendly, accommodating and professional. The facility is extremely clean with easy access. I do want to make special mention of the staff who went above and beyond to help us when our rental truck broke down enroute and needed to be towed to our unit arriving after hours. We can't thank them enough during a tough situation. 5 Stars and will always recommend.

The friendliest, cleanest, and most convenient storage facility I've ever used; the kids always appreciated the handy restroom and enjoyed the candy stops while I liked the easy payment options. Thanks for a great experience!

Recently my husband and I found ourselves without housing due to a family emergency. We ended in temporary housing for 33 days and utilized a storage unit for about 6 weeks. Remarkably clean lot and unit. Secure storage with a great lock provided. Snow removal from lot was swift and complete during significant seasonal snow storms. Nice couple greeted us, checked to make sure we got into unit that first day. Also appreciate them being present at the site including out on the actual storage lot. Made me feel like my belongings were very secure and that they cared about their customers. Would definitely recommend to others.
