    My equipment was stolen. After getting a bigger unit. They asked me what am I storing, I told them that was a big mistake. Two months later, everything gone.No, help from anybody inside job. No one rent from exstra space walnut drive walnut ca there is 5 other people I found on yelp samething happened to them they don't call you back nothing im in process of talking with their corporate office in utah I have a very good friend that has a close relationship with someone in the , corporate office I am not the first one to pursue this the truth will come out the funny thing is, they review their reviews. And they will leave a comment. But you can never get ahold of them, and they will never call you. It's a joke.this is a inside job . The district manager should be the one calling, but they don't reply to them. Telling them because there hiding something district manager should be calling. The victims or victim and reviewing the videotape. It's been 3 days now. No phone calls. Im not stopping Intel people are investigated I dont want this to happen to other people.. so my voice will be Hurd and im all ready communicating with the investigator . There is so many bad reviews on Yelp and Google's about people saying it's an inside job. This is crazy. ... Read more

    Joanna was my advisor. She was very knowledgeable and patient for a first time storage rental customer with a lot of questions. Place is clean and quiet. One thing to be aware of is that the entries/exits has fairly steep approach angles. ... Read more

    I was very gratefull for how nice and how well they worked with me getting my stuff stored. However, it would be nice if storage companies would go back to being just storage companies instead of being money hungry. There used to be a time where you could store your stuff and not worry about it. Now, they insist upon raising rent and letting you know that it's supposed to be temporary. Which really makes no sense whatsoever. You make money off the storage of every unit. There is literally no issue with someone storing their stuff when you make money every month. Make it make sense. ... Read more

    The inventory manager Austin is super helpful and tries to get me the best deal possible ; the Walnut branch manager Jonathan is also very friendly and knowledgeable.
