You can meet me near the Taxi Station of the square. If you're coming by car, the meeting point is very close to the parking places.
The tour can end inside the restaurant or in a convenient place for you close by.
If you will need a pick up, you can send me a request and I'll check if I can pick you up because it's near the Meeting Point 1 (Piazza Sant'Agnese 1) otherwise, I will send you the price of an additional cost for the transportation.
