The service here is above and beyond whatever you might expect out of a storage facility. I had cleared my unit out for a move-out. I had left the lock on to remove later but had to leave town quickly for a family emergency. Tea, the manager, was very understanding and cut the lock for me without the normal fee.

Tea and his maintenance worker, Miguel, were also super helpful and took care of a mark left by some leaking equipment that I had started to clean but didn’t get to finish up on. This is the kind of stuff many other places would have used as an opportunity to get an extra $100, and instead they decided to help out the customer instead. It’s a rare thing nowadays.

Besides the friendly and accommodating staff, the place is spotless and easy to access. Just keep an eye out on your bill, as the monthly pricing made two big jumps over a short period of time.
Response from the owner:We are glad to hear Tea and Miguel provided exceptional service during your emergency. Thank you for recognizing their understanding and helpfulness.

Very professional and helpful with my current needs. There was no face to face meeting. Everything was done thru phone and email as to keep contact to a minimum. The units and facility are clean and priced reasonably. Thanks.
Response from the owner:Thanks, Nathan! We're so happy to have provided you with a 5-star experience.
