We are so pleased that we booked Costanza to show us around Siena for 3 hours. It was a fantastic introduction to the city and we learnt and saw so much that would have been impossible even with the aid of the most detailed guide books.
Her knowledge of the history, art, monuments and even geology of Siena is so impressive but delivered in a wonderfully relaxed and friendly manner. It felt like talking a walk with a friend, albeit one who just happens to know the hidden parts of the city and the intricacies of the contrade!
She really helped us to understand and appreciate Siena and more fully enjoy the rest of our stay. If we return to the area in the future, then booking Costanza once more will definitely be a priority!
