HI, we are twi students from London and we want to spend a week in Tuscany. More than the site seeing of cities we are interested in the landscape and experiencing the local culture, do some hikes, take cooking classes or wine tours. We are on a super budget trip and will have no car. Hence ,we will be dependent on public transport. We intend to fly to Pisa. Can you please guide us with a feasible itineray?
