05-09-2026Took 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.
