Paris has lots of nicknames, like "City of Lights" or "City of Love." For me, it’s the “City Where I Once Spent Just 24 Hours”—and where I had the most magical time, stuffing my face with croissants, watching a racy cabaret performance, and visiting the Louvre (but not to see the Mona Lisa). While I hope you get to spend more time here than I did on that visit, if you only have one day you’ll be able to see a lot more than you think.
