    Easy process and clean facility.

    My move in went well. I was lucky to get a load in spot as there is only space for two vehicles to drop off at a time but it all worked out.

    Size not accurate

    I rented a 10x18 but that is not what I arrived to find. It is a triangular shaped storage which made it exceedingly difficult to modularly pack my things in. I feel like I was scammed but with the movers there with my things on a Sunday and a plane ticket the next day I didnﾃ｢竄ｬ邃｢t have time to wait for another unit.

    Really clean

    Brand new building. Super clean. Only issue is I almost got stuck in the elevator trying to move close to closing time.
