Casey on 05/13/2025
Amy is a wonderful manager that lives on site and that makes me feel like my belongings are really safe. After calling around to 5 other places, I settled with American price wise. I did Public Storage first and when I showed up, My entire unit was 2 in of water and all the other units nearby are also in water due to all that rain that we had but still.. I quickly decline their services and paid the extra money to drive away in the moving truck for a day more. No way I'm going to take a chance on a storage facility that isn't protected by flooding water. Public Storage was cheaper but they didn't have an on-site manager there to help handle the problem Not only that but they refused to refund me for up to a week of fighting back and forth on the phone. So if you want to save yourself some extra time and they have some vacancy, go with American Self Storage“
