My friend is the one with a.storage unit here. I went with her the other day, it was interesting. It is kinda built on a downward slope. So it was very interesting watchin her try to get her motorcycle in the little space, had to assisst In getting it in there. Quite comical im sure. But the facility was koce, clean. However I think someone is living In their unit. Which is kinda un comfortable all in itself.

I don’t recommend renting from this company at all. Staff are cool.
However, after 1 year of renting, I’m glad I finally left. They are EXTREMELY overpriced when compared to local competitors. My rent was 77 a month for a 5x5, with a $10 rent increase after a year. During this time, the establishment did nothing to reduce the rampant mouse problem, which didn’t justify price hikes when there is a clear lack of upkeep on the building.
I was able to find an indoor climate control 5x5 unit for $56 per month, a far better deal and building than this place. Do not support them. Especially when their responses to their customer concerns all get hit with an automated message.

Very nice lady that runs the place there, she went with me to make sure that I got in the right unit and understood how to use the lock on the door and make sure that it was going to be the right size for me. And she’s made sure that I understood that if I had any questions or problems to let her know and she would do anything she could make things good for me. Nice clean unit. I’m happy with the area that it’s in.. And I would recommend these guys to anybody that needs a unit for storage.
