Overall good experience. Prices were very reasonable.



I felt that my things were safe in the facility. Also, every time I needed to get in contact, I was met with a quick response. Even on weekends or at odd hours. It was great.

This company charges a "non-refundable deposit". A deposit gets refunded, so this would be a fee, period. Aside from that completely satisfied.

Barbara D. on


I only visited during the day, so I don't know if the facility was well-lighted. The units seem secure. Staff was very helpful and personable. Facility is clean and units close tightly.
