I was quite impressed with the staff. Or should I say, Kayla. Very informative, friendly, answered all my questions to the best of her ability. Unfortunately, I moved further than expected so opted to storage closer to my location. But I'm always changing locations and will choose this storage if I find myself back in E. Wenatchee again! It is a very secure and clean facility. Thank you again Kayla!!!

The service, care and attention to detail are stellar at Additional Mini Storage. Their units are clean, on-site manager is friendly and thorough. The upkeep of the grounds is appreciated. I especially loved when trees were removed so I could see traffic better when pulling out. A+ in my book! (Customer for 6 months)
