To start, the facilities here are very well-kept and organized. More importantly, I had to cancel my lease due to personal circumstances and Monica was extremely helpful in assisting me with a refund. Would definitely rent here again. 

Business response:

Thank you for the kind words, Gene! We're committed to providing excellent customer service and clean facilities. We're glad to hear that Monica was so helpful to you. Call us at 888-storage whenever you need us.

Setting up the account was easy and the place is super clean and secure. I love how I can just go whenever I please during their hours and access my things without someone there. Great system! 

Business response:

Hi Mary, thanks for the great review. It's wonderful to know you were met with a clean and secure facility. Please give us a call at 888-storage if anything comes up!

3 months into storage (after starting June 2025) they doubled my storage rate from $84 to $168 and only notified me via postal mail. Not even email notification after I paid until I got a charge and receipt. Double is crazy... then I had to call and talk to multiple people to talk it down to $104 while they still had a plethora of open units open that were less expensive. Update: July 2026 -- they again nearly doubled my rent to $184... without texting, calling or emailing. This is just bad business.

They raised my monthly rate by 76% after just four months, from $131 to $231! That's extreme bait and switch. They do this after you get all your stuff moved in, in hopes it will cost you more to move elsewhere than pay the much higher rent.

Walked in the office on Friday and asked for a 10' X 30' drive up space , lady in the office took me to the storage and showed it to me and I liked it then she offered me I can put it on hold for you for 4 days I said awesome I'll be back Tuesday morning to sign a contract and pay for the first month and she said perfect we'll see you Tuesday, Monday at 2:30 she calls and says the unit has been rented out, I canceled the other spots I took a look to take this one but they prefer money over customer service

This business has terrible practices. My rent just went up 38 percent! I've only had the unit for a small time. Just a few months. It was not an introductory price either and I've read others having gone through this as well. I will be moving my things before they charge even more. I was not even notified! I would steer clear of this place they are thieves. I also double checked and the rents are listed the same as when I rented so this is not an increase due to demand. There are plenty of empty units as well. This is a ... read more

What a scam! They get you in under a lowish monthly rate and then after a couple of months, they regularly increase the fees. Not worth it and I can't trust this company. I should have trusted the negative reviews from the start. I hope you will.

Periodically, we reassess our rates to ensure we can maintain the quality of our services. We'd be more than happy to explore any available options to help lower your monthly rate. Let's discuss further! Give us a call at (510) 903-3666.
