Or you could take the train
Very easy, cheap and quick

Unless you have mobility issues, taking a bus (from the airport there are many) or a train, will be much cheaper (less than 8 euro per person vs. 120+ euro with a private driver)

Thank you both for your responses. We are older sisters, 72 and 80, and wd like a car service. So that info is very helpful
