    Seems like good affordable storage

    I was looking for storage at low price. The facilities look clean. I have very little opinion as of now, as this is the first time that i am using self-storage.

    Friendly & helpful stuff, reasonable price

    So far very satisfied with Csptain's. Friendly and helpful stuff, easy access and seem secure enough. No visible issues after couple of rain storms. Convenient pay schedule - month to month and options to upgrade/downgrade with credit transfer from previous account.

    It was very easy to understand, from the way the Latina girl in the office handled all the necessary paperwork and the use and rules of the facility, I like the wide roadways and the access to the units.

    Captains storage has plenty of three month discounts,, which is what I needed. I did not have to sign up for a long term rental and was very pleased with the service and the time it took to get in and out. Great Deal, kind people and no long term commitment.
