I would rate it 70 out of 100.

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

There was no Citroën at the airport, so we were given a larger Volkswagen Multivan for the same price. Fortunately, I'm an experienced driver, so it was no problem.

Initially, it was agreed to return the car with a full tank. However, upon arrival, they required an empty tank and charged 67 euros for fuel. The staff was inefficient and kept chatting, taking an hour to complete a single process.

AVIS and Budget share the same counter. There were quite a few people picking up cars at Rome airport, and I waited for almost an hour. The car was in good condition, and returning it was even easier. Since the fuel was used up, the return desk just took the keys and signed off, and we were good to go. Very convenient.
