    Read some helpful reviews of Extra Space Storage, shared by real renters with genuine experiences and honest opinions.

    Amazing service by the onsite manager Diego. Truly one of the most coolest managers Ive ever met. Always ready and willing to help as well as being incredibly easy to talk to. Highly recommend My only note to higher ups within Extra Storage. If im paying for a space, i should have 24/7, 365 days a year access to my unit. No hours should prevent me from being able to load in/our of the storage space. Diego, great! No 24/7, awful ... Read more

    This is a great storage unit as there is always someone in the office during standard working hours. If it is outside of their standard hours you can always speak to someone on the phone. The facility is clean and well it. The management is responsive and always addresses any matters that you raise. ... Read more

    Nick F. - 20 June 2025
    I contacted Extra Space Storage because my present storage company Has no one on site to handle issues and is self service/kiosk only. The first person I spoke with, was very easy to talk with, and we worked out a great deal. I then spoke with Veronica, who was very helpful and finally with Connor, the property manager. Everything has been very smooth. They've accommodated me with a space that's easy to load in because of the location and convenient. I look forward to a long relationship with this property! ...

    George S. - 24 April 2025
    I have had a unit with Extra Space for almost three years, when it was still Life Storage and it was a smooth transition. I have never had any issues and I would recommend their services to others. Veronica and Troy were the only employees I have had encounters with and they were always friendly and helpful. ...

    Kei T. - 4 March 2025
    1. I rented a unit for less than $40/month with life storage. Then Extra Space bought the life storage. I think the Extra Space just want more money from their good customers, the company raised my monthly rate to more than $70 after 3 months! There was no emails, no phone calls and no text messages in advance to warn me the rate increase. 2. No prorated refund when I moved out after 10 days of the billing date. ... Read more
