Early taxi for flight from Florence

You can call, taxi, use an app, ask your hotel desk to call. They'll be there in 5 min.

You need about 15-20 min to drive to the airport. The airport is small with few flights. If you get there one hour prior to departure is enough.

I usually reserve a taxi the day before and find the car waiting for me at the agreed hour. Takes the anxiety out of the whole process. Have your hotel reserve for you or phone 055-4390 or 055-4242.

Thanks so much to both of you. I will sleep well the night before my flight knowing I can reserve the taxi. You guys at Rick Steves are so very helpful. His books are great too.

Just for the record, the people that responded to you don't work for Rick Steves. They are just interested travelers with knowledge of the city who help out people by answering questions here!! indeed, the Rick Steves company does provide this forum for the exchange to take place, and his employees stay on top of the Forum and sometimes respond here (they will be designated by their name that they are employees).

Enjoy Florence!
