I just moved into a unit here a few weeks ago, and I have had an excellent experience so far. Joelle and Christine(spelling?) Were exceptionally helpful. There are a few move in perks, which when paired with nice facilities and amenities make this a great option for storage.
My only issue has been the need for noise canceling ear buds/headphones because the sound of the carts rolling down the halls is LOUD.Facility Amenities
