Except for the unpleasant pickup experience, everything else was very satisfactory

Very dissatisfied. The original vehicle was unavailable, and I had to either downgrade, pay more for an upgrade, or cancel the order.

The rental company had a guide who was very polite. However, the person who assisted me during the rental was not very professional, especially since he kept speaking Italian to someone else while talking to me. Most importantly, I ended up paying almost double the rental fee, which was very irritating.

The car we booked wasn't available, so they upgraded us to a Volvo V60. Although the rental cost increased a bit, it was still worth it.

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

The car model we booked was not available at all. When we showed the contract to the staff, they didn't care and said that the model in the contract was unavailable. We had to either accept the available model or not rent at all. Since it was midnight, could we really not rent? We ended up reluctantly accepting a smaller model. The trunk could only fit three suitcases, and we had to place another suitcase on the back seat, making the back seat extremely cramped. The journey was very uncomfortable!
