Signing up was super fast and easy with a new electric lock. No need to find or forget my key. Only wish there was a restroom in the outer area for easy access. Facility is very clean. I’m happy.“

O’Shea was the customer service representative that assisted my daughter and I with selecting a storage unit. He was very knowledgeable about the various questions that we needed answers to. We appreciated his expertise to help us make the best decision in choosing a unit. He has a professional and respectful manner. Of course we would recommend our friends and family to your company for O’Shea’s excellent customer services.
Sincerely, Frieda G.Mosley
