We were able to buy tickets when we arrived, which was convenient. Students can get tickets for €8 and I was not asked to show any ID. There is very minimal signage and none of it is in English, but they provide a pamphlet in multiple languages with helpful information. The views of the city are great and you get to see everything from a completely different angle than you would from the street.
I am directionally challenged and got turned around a couple of times, but it was still easy to find the way out. I am 160 cm and did not feel like the space was small, but my friend who is 170 cm had to watch her head in a few spots. If you are taller than 180 cm, some areas may feel low and not very comfortable to move through. Overall, it was worth the visit.
