You can rent a car by yourself immediately on arrival - at the airport, at the train station or at the nearest office rental company. The car is better to book in advance via the Internet, to be sure that you get just exactly the car you need. It is recommended to use the services of the rental company with a worldwide reputation: Hertz, Avis, Budget, Eurocar, AutoJardim, FacilCar, Irebent, Mundirent.
