This was one of my favorite parts of my recent trip to Rome. I would recommend it to any film buffs and/or fans of the HBO show Rome, but you need to take the guided tour for the best experience. The only issue I had was with the booking was that I thought I was booking for the guided tour but it turns out it was only for the exhibit. I asked for clarification on this twice through the booking agency and got no response. I was able to take the tour after all, but I would not have been happy to arrive there and find I could not. The site needs to be clearer.
