    California P. - 11 March 2026
    Talk about Bait and Switch! These predatory deceiving shameless thugs went from $89/month to $189/month at the end of my initial contract! I had to deal with a broken gate for about 7 weeks by being forced to enter far away and had to wait a few times for other tenants to move so I could get through the only tunnel to get to our storage. I will definitely be OUT AND NEVER USE THIS COMPANY AGAIN. I tried calling and the representative(Jacob) "helped me" by offering me a $179/month offer. What a joke! ... Read more

    Was super fast and easy. I was able to reserve my unit and price on-line. They called me the next day to see if I wanted to get/setup my unit over the phone or online. But because I had already withdrew the money I want able to that; plus I wanted to see the unit first. Only thing is the office is closed on Sunday so I had to wait until Monday. Customer Service and Staff are very friendly, courteous, professional, and patient. Thank You. ... Read more
    Patricia M. - 7 March 2025
    I had my unit for almost a year. The costumer service is good. I did get an online deal but sadly after 3 months of use they raised it $30 dollars which was disappointing. At this point I couldn’t move my items. The only issue is that they have very limited carts and people don’t put them back so you’ll find yourself looking all over the warehouse to find one. Just keep in mind that if you store on the second floor the roof leaks and causes moisture in the units. They have containers catching the water that leaks from the roof all over the 2nd floor. If you have moisture sensitive items I would consider storing elsewhere or the 1st floor only. The lift is very sensitive. You have make sure you follow the instructions properly. Overall it’s a safe warehouse and extremely convenient. It’s close to the freeway and trolley station. ... Read more

I am giving Extra Space Storage a 10/10 rating only because of this Angel. I will recommend this storage facility to anyone.
