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!

I visited Extra and it was perfect timing because I was helped by Micheal. I was in a pinch and really needed to urgently find space while waiting to move into a new apartment. He made the process clean and simple. Thanks again I’m definitely recommending this location and Micheal.
