Good afternoon, everyone. We have not been directly to this place. I'm just sharing my experience.
It's really expensive!
As an example:
We were in a similar place, also the cost is 3 euros per person. It is written at the entrance. They ask for 10 euros. It is unclear from where and why?!
But we were with friends, they are local.
They talked and paid 200 lire for six people 🙃
