For starters, the pricing is the best and a lock comes with the unit. Thereテ「竄ャ邃「s to bays and the elevators are right there. Itテ「竄ャ邃「s cool inside and Iテ「竄ャ邃「m moving in 100 degree weather. Big win there! Super clean and the layout is great. I was super stressed about moving my things into storage but when I showed up and started moving, I was beyond relieved thanks to this space. Iテ「竄ャ邃「ve had to use storage many times and this please is by far my favorite, HIGHLY recommend.

Great facility.
