In order to get to Petrolo Winery you must come from one of the main airports. You have a few options of how to get to the villa.
1.) You may rent a car and drive yourself
2.) Take a train to the nearest city of Mercatale and we can pick you up there
This airport is about a 45 minute drive to the villa, it is the nearest airport.
The Rome airport is also an option. It is about a 2.5 hr. drive to the villa. If you choose to fly into Rome and are not planning to rent a car, I recommend taking a train to Florence and exploring here for a day before heading to the villa. The train schedule to the villa is typically not convenient from Rome and is much more convenient from Florence.
