I will be staying at Hotel Retrome which is located in Via Marco Aurelio 47. We have a flight from Rome(Fumicini) to Paris on 21 May at 7am. I would like to know what is the best way to reach the airport at around 5am in the morning to catch the flight. I wrote to the hotel and they are offering me a cab at Euro 55. I am not too sure if the rate is fine or if there are cheaper means of reaching the airport.Is there a reliable taxi service that you can recommend? Should I book the taxi in advance or wait until I am in Rome?Any help would be greatly appreciated.
