Welcomed immediately upon entering the office. I was given clear instructions and guidance of the facility’s layout and rules. The facility is very clean, easily accessed, well lit in the evening. Pricing is slightly higher than I originally planned on but the convenience of location is worth it. Would recommend this storage facility.

Thank you for your wonderful review and recommendation, Bridget! We're so glad to hear that our team provided clear instructions and guidance, and that you found our facility to be clean, easily accessible, and well-lit. We understand your comment about pricing, and we appreciate you recognizing that the convenience of our location made it worthwhile for you.
