I’m French so I know Paris well
There are many things to do.... you can visit Eiffel Tower, the Louvre, Walt on the Champs Élysées and do shopping, take the « bateau mouche »... There are also many beautiful places like Versailles or Chantilly but it’s more outside than Paris 😁
While it's outside of Paris in the town of Chantilly, The Living Museum of the Horse is a must see for equestrians. It's a massive stables that was built by a prince to serve as his home in his next life, as he believed he would be reincarnated as a horse. Really cool place with a great collection of pieces to do with riding and horsemanship throughout history.
Hey Hannah, my boyfriend took me to Paris during fashion week 2 years ago… It was a dream! Here are a few places you should absolutely go to (besides the museums and monuments that I am sure your hotel will indicate you as the must see places in Paris): Costes restaurants, Versailles Gardens, Louis Vuitton Foundation, some very good restaurants (Robuchon…), Lemarais for a more artsy and young atmosphere, the Prescription club for drinks, the Tuileries, Bagatelle Gardens (not if you plan on going to versailles already though), and Faubourg street for shopping and lunch… Enjoy your tip, really hope that you'll have the opportunity to go there. :)
