Really good one day tour at an excellent price. We met our excellent guide Elisa at 8am and took the coach to Siena, where we were joined by another guide who took us through the colourful history of the city and around the huge ornate cathedral (included in price). Earpieces were provided to ensure we could hear clearly at all times. Although we hadn't booked the wine tour and lunch, we were offered the chance to pay a bit extra to join that part - and glad we did. The food was really good and wine plentiful.
We then spent a little over an hour at the ancient medieval city of San Giminano and tried some gelato from a world championship winning gelato restaurant, before the final stop of the day at Pisa to view the Leaning Tower and back on time to Florence. Only slight downside of the trip was some longer walks from the coach stop to sights, but assume this is to keep the price down.
Overall a fantastic day out in Tuscany and great service from the guides and driver all day.
