Extra Space Storage on Fremont in Sonoma is clean, in a great spot it has good security, every unit is driveup and the biggest reason I stay there is the Manager, JB F. I’ve stored with him at another facility before and followed him here because I know my stuff is in good hands and feels safe with him.

Thank you for your continued trust and loyalty, Deon. We’re glad to hear JB and our team have provided a clean, secure, and dependable storage experience. We truly appreciate your business and are grateful to have you with us.
