We will be arriving at the Pisa airport with 3 children and my in-laws in mid-September with a total group size of 7. We are going to the town of Greva in the Chianti region where we have a villa. We will be doing some days trips during our 2 week stay. We are debating on car rental vs. train. I need help with public transporation options from Pisa to Greva if we don't rent a car. Is it train and bus? How long? Prices? Which companies? Can't seem to find airport transporation on the web from Pisa. Any ideas on good private driving companys to pick us up and take to the Villa and then maybe a car rental later?
