    Just viewed my unit, got a really nice tour of the ground, where doors are at, how to use the app, find carts, find bathrooms, etc. Amazing customer service and so friendly. I’ve only had one other storage unit prior to this and it was so impossible to get a hold of the people and they were never in office. I am so glad to feel comfortable that if I ever have questions or need help, it’s there! ... Read more

    I had been using BestBox since around its opening in late 2024. The other day I had a few questions and talked to Melissa. She was extremely helpful in answering all of my questions and assisting me in finding the best options for my storing needs. She’s a true rock star and the facility is secure, clean and has plenty of tools (such as flatbeds) to help move your items in and out. Thanks to Melissa and Best Box for the help! ... Read more
