Our guide Victoire was a 5+ star guide!!!! She not only was extremely knowledgeable, but her passion for the history, the stories, the current state of the catacombs rubbed off on me and my niece! She was also patient with all of us taking photos, and in answering our questions. I wasn't sure how much I'd enjoy the tour, but it turned out to be one of the highlights of our 2 week vacation in France. I highly recommend the tour. I rated 4 star because it was quite expensive.
