    I would recommend not storing items here. I have an inside unit and noticed the entrance door is often left open. My unit was broken in to and was only informed by the Arvada police when they found several of my items. While I was reporting the break in to my unit to the Thornton police another woman pulled up saying she had her unit broken in to as well and reported it to police just 2 days before. I feel it’s not secure and would urge you to stay away

    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.
