    Quick Access

    When I arrived I inputted the access code and stored away my belongings in my unit with such ease and confidence. I highly recommend this service to anyone looking for a place to keep their property in a secure unit for the duration of their purchasing.

    Great So Far

    I really donтАЩt like being asked to leave a review of any place right off the batтАФI literally JUST moved my stuff into the unit yesterday. IтАЩd like some time to see how things go first. Which is the only reason why I gave 4 stars instead of 5. That being saidтАж so far the experience has been very good.ЁЯСН The whole place is very clean, very secure with redundant security measures (which I appreciate!) and the price for my size unit is very good. ItтАЩs in a decent neighborhood, no sketchy surroundings. They have carts available to use for no extra charge.ЁЯСН I was a little worried about the unit being on an upper floor, even with elevator access as IтАЩve got back issues and more. But with the carts and elevator I had zero problems. When I checked in with the manager (I believe her name is Rose) she was very friendly and very helpful. I liked the whole process of being able to find what I needed and do everything online without any hassle or gimmicks or tricks, including up front pricing AND being able to just go ahead and pay for the unit if you want toтАж or just reserve it so you can go take a look in person before pulling the trigger. The ONLY thing IтАЩd recommend so far is that they give you a MAP of the building your unit is in. ItтАЩs like a maze inside with so many units per building and no signs indicating unit numbering. Other than that, my overall first impression is very good and worth leaving a preliminary review. If that should changeтАж so will my review.
