In a event of an emergency !!
I was forced to moved within 2 weeks this place was a life saver I am fearful that I was able to receive super fast service for storing my household items and clothing. It was super fast reliable and easy to create an account online. The staff (Donia) at 3503 B street was very friendly, helpful, and informative about the entire process. Thank You self storage I really appreciate it !
