People always ask: "Anybody know a good driver to hire in Rome?"
Look no further. Pasqualino is the best. He comes highly recommended.
Italy Ride has their site in English: http://www.italyride.com/.
Nicest people. And they speak English. Punctual, friendly and knowledgeable.
Hire them to drive you to and from Fiumicino airport or the port at Civitavecchia. Excursions in and outside the city. Day trips in all directions. I have been highly satisfied with them and highly recommend them.
