to visit several times because they are too large.
a nice experience.
they could probably be enhanced even more.
a few more signs (or rather some signs because there are none) would be useful to guide the visit even for those who take the video guide.
It is a labyrinth so it would be useful to give some more explanation.
groups organized with a guide should have headphones so as not to disturb other visitors.
We paid 22 euros of ticket plus video guide each. However, the ticket only reads 16 euros.
