Awful experience. If you have a unit inside look elsewhere. The hallways are ridiculously narrow, I couldn`t even get my sofa around one of the corners to the unit.

Greg M. on

Rating:

The one minus was a lack of turn-around space - necessitating navigating our trailer hitch in reverse through the security gate, which was maybe a foot wider than the trailer.

KELLY M. on

Rating:

I highly recommend A+ Storage. They were extremely accomodating and helpful. Their store also sells everything you need for your move at very reasonable prices.

VANESSA F. on

Rating:

Great service and very clean facility. Big caveat: online ad rates were cheaper than the actual chargeable rates.

VICTORIA P. on

Rating:

We were unable to rent this storage space because it was to small and the company didn't have something larger available, the clerk sent us down the street to MiniU Storage.
