The location is perfect, very close to Notre Dame, Louvre and Hotel de Ville, and a couple of blocks from river Seine. There are lots of restaurants and street food vendors at the back. Most of the Metro lines converge at Les Halles and Chatelet, only steps away from the apartment, so it’s easy to reach all parts of the city with public transportation.
The checkin was not very intuitive and the QR code we downloaded failed to scan, but the host was on call to give passcode to open the doors, so not a big problem. A handyman worked right outside the apartment door the day after we arrived, and left a very pungent odor, likely from some kind of industrial adhesive he used. Because the space is small and closed, the smell lingered throughout the entirety of our stay, which was not very pleasant. Our flight was in the evening, but there was no place to store luggages during the day, which required us to make reservation and finally carry our luggages to a place blocks away, but I don’t know the local practice well enough to tell if that might be par for the course in terms of Airbnb stays in the city (hotels certainly would not have this problem and hassle).
The quibbles aside, we were generally happy with our stay, and would recommend this place.
