    Spoke to Stefan ((or Daniel?)-- Sorry, memory issues) to finish setting up rental & get further information. He was awesome! He took the time to explain some things I had questions about. I feel like this is going to be a great rental experience if this level of service continues. Thank you again, Stefan (or Daniel ?). ??

    First time using a storage facility. The manager was really friendly, efficient, showed me the options available and different unit sizes. There was a website special! Facilities are very clean and safe. Thanks!
