Storage Customer Reviews

Bonnie C. | Overall Experience |

This facility is very nice and customer service is exceptional. The whole time that I have stored my belongings at this facility and in Norman they have been safe and secure. The manager is always out on the property making sure that nobody is doing things they shouldn't and watching out for your stuff.
