    James was so helpful! This is a wonderful location. I called in about 8 AM this morning; I didn’t know they were closed and he unexpectedly called me back soon as they opened. I completely forgot that I called. He made everything easy to understand and provided amazing customer service. I really appreciated his help!

    I had an appointment at another ExtraSpace facility but no one was there and the main office was completely unhelpful. I decided to take a chance and go to the Mariner Square facility. There, I met Riley Brown who was just completing a transaction with another customer. Riley was extremely helpful as I explained that I wasn’t sure what size unit I needed because I’m more a visual person so they took me through to see the various units available. It was a great experience. Riley certainly understands customer service and it was an absolute pleasure doing business with them. I highly recommend this facility.

    I’m sharing my experience here so others don't end up in the same position I did. My unit was burglarized, and I lost irreplaceable personal items. The incident was officially reported and classified as a burglary by the police under California Penal Code 459. Despite the police report, the facility's required insurance policy denied my claim completely. Because the person managed to get up the elevator and open the unit lock cleanly without ripping the door apart, the insurer claimed there was no "proof of forced entry." I need you to warn people considering this facility that there are major security gaps in this facility. Someone was able to get into the building, use the restricted elevator, and open my locked unit without raising any alarms or triggering a response from management. The insurance they provide is actually a trap, you are required to have coverage, but the fine print requires obvious physical damage to prove a break-in. If a thief bypasses their locks or uses a clean workaround, the insurer considers it unproven and pays nothing. The Management was unhelpful throughout the entire process and hid behind the lack of visible door damage to wash their hands of any responsibility. The way this facility operates leaves you entirely unprotected while giving you a false sense of security. If someone manages to access your unit cleanly, you will be left with zero recourse for your stolen property. Save yourself the headache and store your things somewhere else.
