Good service organization, maybe at the entrance a bit confusing because of the many people. The queue jumper is indispensable. The staff at the entrance is a bit cold to those waiting in line. The guide who takes you to Do the hike on the other hand is nice and knowledgeable.... The steps seem like a lot but they are actually wide and comfortable. Recommended

It rained a lot on the day of our excursion. It was a bit of a hassle as we had to wait outside in the queue for almost half an hour. We were there an extra 15 minutes beforehand. Afterwards, however, we had a great guided tour through the tunnels of Naples. Bex explained everything to us in very good English. It was very interesting. Thank you very much. We would book this again.

We had a very enthusiastic and knowledgeable guide. He spoke good English and was charmingly eloquent. My only criticism is that he could have helped us more to understand the ideas and motives of the people in the seventeenth century and emphasized less their strangeness and the apparent greed of the Dominicans.
