I appreciated hearing many "new-to-me" stories about Napoleon, Louis XIV and other significant figures of the time. I heard new stories related to the Obelisk de la Concorde, Place Vendôme, etc.
However, I thought it would be more of a walking tour and instead we made a fairly small circle and only stopped at 2-3 main places. I also thought the stories dragged on a bit and we would stand still for 10 minutes sometimes just listening to quite a long explanation. I think the pace could have been a bit faster and maybe more linear. I feel like we bounced around a lot in the historical timeline.
Overall, okay, and I'm glad I did it, but you should really want to hear a lot of details about Napoleon and not as much about the landmarks / architecture.
