We have rented at this location six different units over the fourteen years we have lived in Castro Valley. The staff is always very courteous and willing to help you get the right unit for what you need. We have had drive up units as well as interior hallways. They are temperature controlled. It is safe and secure here. I am grateful for my experience here.

Easy fast reservation online. Went into office showed ID initial this and that pay the man got my things into storage made me realize what I wanted to store wouldn’t fit in unit I was getting without pressuring me to rent bigger unit. Didn’t want to see me do the extra work in this heat.
