    Kristina and Shane at Cook Street have been extremely helpful navigating the storage unit rental and storage unit transfer process! The company’s overall billing system would benefit from greater clarity, transparency and communication, and less predatory policies.

    Shane is excellent. Very helpful and friendly. Went above and beyond to make storage easy for me! Facility is clean and well kept.

    Shane was SUCH a huge help! He was knowledgeable and didn’t hesitate to show us units that would be the best fit for us. The entire building was SO clean and beyond well maintained. I cannot recommend this facility and Shane enough

    Very easy setting up the storage unit. Shane was extremely helpful showing me the unit and how to get in and made the overall experience wonderful.

    Was a breeze setting up a rental unit online, very competitive pricing too. Got an email with all details needed, drove to the storage and was easy accessing it. Clean, well maintained space overall and good option of storage unit sizes. The only suggestion (not sure if I missed it if already available) is maybe a map so that it’s a little easier to locate the storage on the first visit but otherwise has been good thus far.
