With Hertz, there were quite a few people, but it was still manageable.

Hertz rental company has a cold attitude towards Chinese people, not as good as Avis! When picking up and returning the car, no one interacts with you much, and they don't even provide receipt documents. Moreover, they didn't inform me about DEF for the diesel car, causing me to worry for a long time and pay an extra 15 euros for AdBlue.

International company, very quick pickup and drop-off

The car had PLENTY of dings and scratches, many of which I had to point out when picking the car up. They don't have unlimited mileage on our car rental, and we only found out about this after we picked up the car. When we returned the car, we had to wait about 40 minutes in line, thankfully we got to the airport early. We were happy to pay the charges, but when we received the receipt and asked our service person, they kept giving us vague answers that didn't make sense. We then went into the manager's office who then proceeded to say that in Italy, there are taxes on taxes. Okay? What does that mean? He wouldn't go on to explain any more. Just beware of hidden charges at Hertz, Dollar and the rest of the fleet, just another typical car rental shop that sends you hidden charges upon return of a vehicle.

Staff at counter was very rude at drop off. Staff at pickup were dismissive and not helpful. Forced car on us we did not want or book. They tried to up sell us to get what we had originally booked. Horrible hertz.
