Jeremy was the best! He was quick and very knowledgeable. Also the unit was super clean and smelled amazing. Most storage units that I’ve been to smell horrible!

Convenient access, app is great. Feels safe and on-site staff are helpful and friendly.
Only thing is the cost - it creeps up and up and up... Almost doubled in three years, to the point where it's just not an affordable option any longer.
I used this site because it is convenient to SFO and allowed me to store my motorcycle and riding gear. At the current cost it's more affordable to just use secure parking at SFO. Notably, the ride share costs from SFO to the storage unit also almost doubled in price!
But, no complaints about the service at all.
