Reviews star rating from customer for A-1 Self Storage in San Diego, California

Put all my personal belongings in a storage unit at this location when I left for deployment. I was slightly concerned because I had never done this before, but Darlene assured me everything would be fine. Sure enough, after 9 months, everything is just as I left it. The facility is kept immaculately clean and the customer service at this location is beyond reproach. Darlene and her team were very patient with me, addressing all my concerns and questions. Highly recommend this location if you are in need of a unit!

The Alhambra A-1 Self Storage is very clean and well lit. My items were in storage for nearly two years and left in the same condition that they were in when they arrived. The office staff were available and helpful during the hours promised, and I always felt safe when I was there. A very positive experience compared to other storage facilities that I have used!

A-1 in Oakland has been great for us. It's conveniently located, clean, easy to access, and the service has been fantastic. I've now rented a unit from them twice, and both times I've dealt with Dena, who's been delightful. She helped me get the same storage unit I'd used previously and even was able to honor the previous rate we paid (I'd only been out of it for a week). Great people and easy storage option. If I'd known it was this easy to get storage in the area, I'd probably have done it a while ago.
