we're planning our first trip to Italy. 3 days in Rome...train to Naples then a private driver to Positano via Pompeii. how do we ind a private driver?
We used Aldo Limos for this exact thing and liked them very much. https://www.aldolimos.com
We used this company five years ago. They were excellent.
We used Monetti Taxi for a private tour of the Amalfi Coast last year, but they also do transfers such as you are suggesting. They were great.
