Don't trust public storage.
They make their employees push services you don't need. They expect them to memorize scripts to overcome your objections, and hard sell you to make you feel that you have to buy. (High pressure sales)
They push there over priced locks, and make you think you have to buy there insurance. The insurance company Willis will fight you if you have a claim. They will also only cover a percentage of your items.
Get renters or home owners insurance and ask if they will cover off site storage.
The reason for this is the district managers, and above get a bonus based on the sales of locks and insurance.
