I would rate it 70 out of 100.

The car rental company is pretty good, but they charged me a deposit that hasn't been refunded yet.

Horrible experience with AVIS rental company! They said the car I reserved was not available, and after switching vehicles, they had me sign a new contract, falsely claiming no additional charges would apply. Upon return, they said the contract included insurance and charged me 1781.88 Euros. I had already purchased comprehensive insurance in my home country and should not have to buy such expensive insurance again. This is blatant fraud! The rental company should help protect innocent consumers like us and support our complaints!

Avis is considered a high-end rental company, there’s nothing to criticize.

The staff at the Rome airport counter spoke very poor English, hardly understandable. They kept pushing for full insurance, and seemed very displeased when we declined. They gave us a subpar car despite our large luggage. At the parking lot counter, they kept stalling and refusing to change the car, only offering a FIAT500 convertible, which was a struggle to fit our luggage into. I was quite dissatisfied with the service attitude of the Rome airport staff, but to avoid affecting our itinerary, I didn't argue further.
