Don't use Public Storage...just don't.
First off, bring your own round disk lock. They will not let you use anything else, and will charge you a whopping $20 to buy their lock. Then, add another $10-$20 to your quoted monthly rent because this place will force you to buy their own insurance even if you have homeowner's or renter's. What a scam.
They kept my stuff safe, but the way they run their business is just shady and not worthy of my repeat business. Avoid.
