I recently booked this adventure for myself and teenage son. I thought it was for tourists to have a creative way to learn about the sites in Trastevere. It is a really cool game/scavenger hunt that is also really difficult if you are not familiar with the area or do not speak Italian. I think we would have enjoyed it more if we had gone during the day rather than at dark as it was difficult to read the clues and navigate places without knowing where we were in the first place or how to speak Italian. The first destination you must enter was a hospital and the door was locked since it was after hours. We walked all the way around trying to get in, not understanding that a guard station was a place to enter. To us it looked like police. Once a guard helped us get in we were in what seemed like a deserted old hospital at night, alone. It was actually pretty scary and I found myself not feeling safe. We decided not to proceed and I let the company know. They did not offer a refund of our 60 euros which I guess I understand but it was worth it for me to stop playing rather than to feel like I was putting myself and son in potentially unsafe locations in a city we are unfamiliar with. If you go, go in a group, go during the day, and go ready to really be challenged. I would actually try it again someday as it did really seem like a cool set up if you had just a bit more comfort/knowledge of the area.
