We have been with Interstate Storage for 8 years. We have always felt our possessions are safe there. The grounds are well lit and we can get to our unit 24/7. Even when there was an unusual flood or rain they handled it with professionalism and helped us get to our unit where all was dry. Any issues we have had they were quick to respond. Highly recommend them! ... Read more
