The morning of 5/19, I was surprised the dollies and carts were not ready to be used and we had to unload equipment ourselves to use them. Tad sp? was VERY helpful and friendly.

The staff was very friendly. They showed us the unit before we signed the paperwork, and it was a pleasant enough experience. They had a few deals, which made the unit even cheaper than expected.

Ashley D on

The staff was friendly and helpful. Little glitches, don`t believe were the fault of the on-site staff, checking in but otherwise a very positive experience.

Rating:

expensive for an unlighted, uninsulated, small door opening storage unit. I worry about possible flood damage, roof leakage, and high temperatures during summer.
