We needed temporary, climate controlled storage after a basement flood. The facility in North Boulder provided us with easy access in a clean state of the art facility. The staff was efficient and friendly.

The storage unit was beyond my expectations. I put my things in storage when I moved back to New York, as I still did not have an apartment, then COV-19 hit. My items stayed in storage much longer than I anticipated, I finally retrieved a week ago. I could not be happier, everything was pristine and no infestations of bugs etc (which I did worry about, but I did opt for climate controlled unit). I have A LOT of books and art, and ALL remained in good condition. The storage unit itself is very clean, well lit, and the staff extremely helpful and kind. 100% recommend - thank you for taking such good care of my belongings!
