Marie and Louis' place is THE BEST location you would want in Paris. It is a short walk away from the Louvre, right next to the Madeleine, and in the heart of the luxury shopping district. It felt absolutely safe, even at night, and it was really easy to access throughout the day.
The flat itself is great. The view is amazing, you can see the Madeleine both day and night. The Christmas decorations on the street were a bonus, too! The beds were super comfortable and there was just enough space for our party of seven.
Marie and Louis are amazing hosts. Very fast responses received throughout the entire process and they made our trip so much easier. We really appreciate them and their flat and hope to one day be back. 12/10 recommend!!
