First time we booked this for our school trip to Italy, but surely we'll come again.
The check-in is a bit chaotic, as nobody clearly takes charge of things. We booked a tour with an English guide, yet he was ill because of covid.
We opted for an Italian guide instead and I translated for my students. Grazia was an absolute star, as she was very occupied with everyone's wellbeing during the tour but also explained everything we saw and did very clearly.
The first part of the tour is underground, with some narrow hallways which the students absolutely loved. The second part is an old house with remains of an ancient theatre.
Grazia was a perfect guide and deserves your preference whenever you can choose a guide. Grazie mille, cara!
