Before I say anything else, I don't want to take away from the significance of this place, and how amazing it was to physically see where both Paul and Peter were imprisoned at one point. That is truly an invaluable experience.
Anyway, it costs 10€ to enter. We did an option with a multimedia guide where they give you a tablet. There was one section that it was beneficial, but the rest it didn't really add much value. The top floor which is really like a museum, did not have much in terms of artifacts or information, but it was a nice introduction to start to grasp what the building was. We walking down to the prison area... There is only a small catwalk that you can stand on. I wish there was seating/more room so that you could meditate/pray down there. We spent a little bit of time down there without disruption which was nice, but I think that was out of luck that the museum wasn't crazy busy.
In conclusion, I would say worth the trip if you want to see/feel a meaningful place for the Christian faith.
