The check-in process was pretty delayed because of u-haul issues in front of me. But it eventually worked itself out and everyone was very helpful. Facility is very nice.

Very nice, brand new, open a week. The gate isn`t working just yet, but they do have a security on site after hours. The check in process was a bit long, but they are learning all the systems.
