    July 27, 2023 - From Extra Space

    ESS is the Apple and Tesla of storage spaces. Cleanest and most secure I’ve found, and customer service is off the charts. Everyone on the phone was amazing and helpful and saved me $$ with their guidance and recommendations and in person, Monica was the absolute most professional, fun and kind person. Thanks Monica and ESS!

    The facility I visited was very clean and new/updated. Rental process was fast and easy and the on site staff was very helpful. The loading dock and elevators make moving your things easy. Highly recommend this location in Alameda on mariner square dr.
