Great Storage with convenient location, good availability and good value for size of unit rented. My wife and I were especially impressed with the friendly and helpful staff. The manager and team made us feel welcome, looked out for us in the hot sun by bringing waters, and proof advice on all things storage.

Phil explained all of the details and ins and outs if renting a storage. I shopped around. Why would i go anyplace else. Im gonna rent from him. Nice man and really helpful.

We're moving to Prime Storage from another company because it's run by people, not algorithms. I so enjoyed getting to know Phil, who took the time to help us find the right size unit for our needs. My experience was entirely positive.
