    Very manipulative

    Was told I would be paying $60 a month for the unit which is a 5x5 unit which I have been charged $110 for for the last 2 months without any notice as to a price increase on the unit

    Superb customer service!

    Trish, the staffperson I dealt with, has been extremely helpful, pleasant, informative and accommodating. The place is huge but extremely clean and well organized.

    Caring and Professional

    Our world has a storage problem, but Extra Space makes the problem less of a hassle with longer open hours than many facilities, clean and professional, well lit facilities, convenient locations and wonderful staff. Old storage unit overpriced, not convenient to get to and quite frankly a scary place for a single person to spend any amount of time in while managing the contents of one's unit. This unit is much more conveniently located, much better lit, doesn't feel so threatening to be in (although one must always remain vigilant at any given time in life) and provides ample hours to access the units. So far, so good!
