Just a little warning to everybody that while there are many reviews of "an excellent car hire" from Enrico Farris in Alghero, all written by the same person, we had a very unpleasant experience with him. frankly, this was the ONLY unpleasant experience of our holidays.
Enrico, who indeed picked us up from the airport and was rather pleasant and spoke OK English, upon return of the car showed another side of the service. While we filled up the tank fully a minute before returning the car, he doubted us and then started claiming it was not full. A month later he sent us some fake receipts of 60 euros (this was the smallest Fiat!) of allegedly missing gas in the car. If it were correct, that would mean that his mini Fiat takes gas for 120 euros to fill up just a half of a tank! Furthermore, Enrico signed for us for taking the money out from our CC. CC company noticed the fraud and returned the money, but the memories of the services remain indeed very unpleasant. If you only can, use another car rental company.
