I stored here for a year and was a rotally satisfied customer. When I needed storage again, I went looking for a bargain at other facilities. What I found elsewhere was a nightmare - shabby, dirty, hot, infested, questionable security, limited access and higher prices. I came back to Castro Valley ExtraSpace Storage where I know the great staff (Shawna), trust the onsite team, love the clean, climate controlled and secure facility.
