There was an insurance upsell when renting the car in Rome, but it was okay. Returning the car in Florence was a hassle just as others described. They nitpicked and claimed a small, barely noticeable mark on the front hood was an accident and wanted to charge a few hundred euros. Arguing was futile due to the language barrier. Although I had been warned to take photos and videos during pickup inspection, such tiny marks wouldn't typically be a concern in my country. So, be extra careful. Luckily, I had purchased comprehensive insurance in my country, so we'll see how the claim process goes. The Chinese customers returning cars after me seemed fine; too bad I forgot to ask where they bought their insurance and what kind they got.
