I can't say enough about how refreshing it was to work with Michelle and the rest of the staff at Mt. Diablo storage. I do reviews when things are great or really bad - they're GRRREAT!
The units are clean and secure and competitively priced.
The front desk staff was always helpful and patient - answered all my questions and showed me as many units as I wanted.
Thank you!“

I was with Mt. Diablo Self-Storage for 3 years, and I couldn't be more satisfied with my experience. From the start, everything was always clean, secure, and well-maintained. The prices were unbeatable, especially considering the top-notch service they provide. The ladies in the front office, Michelle and Alma, were always so kind, friendly, and helpful whenever I had any questions or needed assistance. It's bittersweet to move away, as I’ll definitely miss this place. 10/10 would recommend to anyone looking for a reliable, affordable, and welcoming storage facility!“
