- JJJMay 10, 20265.0Took my mom out for mother's day breakfast at Elio's and found an available 5x5 here for $87.00 on my phone. Ordered it on my phone in less than 5 minutes and downloaded the app. Remote access to the gate via the app and easily found my spot in the back. The place is clean and the 5x5 is perfect for me. Located right near 580 freeway as well. Didnt even have to go inside the office, as my lock was waiting for me inside the unit! The most seamless transaction you can imagine.
- GAGio AlvaarezApr 26, 20265.0Amazing place when you need storage! Dan should get a raise and be promoted for the amazing work he does!
- HCHarry ChenMar 9, 20265.0Great service and friendly.
- HJHeather JJan 16, 20265.0Always clean and easy to use. The staff were helpful quickly with any questions we had. The elevators occasionally go out in the building I was using but I always received a notification if they are out and when they're back in order so I can plan accordingly. At one point I switched to a smaller unit and the staff were very helpful in that process. Definitely will use this facility again!
