We stayed for 2 nights and it was by far the best Airbnb experience I had so far! Richard's place is super sparkling clean and is filled with amazing books, artworks, and special details - together with the view on the gothic church, the place creates a special, cozy atmosphere. The apartment is also in a great location (right in front of the louvre museum, but in a quiet side street). This way we could always be the first in line at the museums and it saved us a lot of time). Also, Richard is an amazing host. He was very responsive, always friendly and thoughtful, and had plenty of helpful travel advice! I would also recommend looking into his airbnb Paris guide here as it had nice restaurants in it. It is definitely worth staying at and is a good value for the price.
