I booked the car for my mom. 1. Person at the counter automatically added "fuel top up" surcharge, which also increased the location surcharge (since it's 20% of the total price), and hence they said she would have to pay the extra when the car is returned. 2. He said if we top it up, then there will be no fuel surcharge, but there was still some money to be paid according to the contract (due to the increase of location surcharge). 3. After I figured this out, we had to ask for a new contract without the "fuel top up" service/surcharge. The original person at the counter was unwilling to help, but the second one happily printed a new contract, on which the correct price was written, where we don't have to pay anything extra (unless, of course, we don't return the car with a full tank). 4. Compared to other southern Italy rentals, I think it was pretty good and good price.
