Facility Reviews

Carol Boser

July 29th, 2025- From Sf

First time I ever rented storage so not sure what to expect. I was pleasantly surprised by the entire process. Easy online reservations. Monthly rental agreement with a discount for the first month. Best part was the staff! They were super friendly and helpful. Provided me several recommendations for my RV storage - photos before you leave in case someone bumps it, face the front out in case the battery drains and you need a jump and use the app to open the gate as you are approaching. Security looks good.
