We stayed in Arnaud's flat for a week during our honeymoon and loved it. We honestly could not have asked for a better host or apartment. Arnaud was gracious and very generous with his time as we prepared for our trip and had some questions to ask over email. The apartment is clean, simple, full of light throughout the day and is very comfortable and easy to sleep in. The location is really perfect! It's easy to walk all over the Marais, it's close to a couple Metro stops that can take you anywhere in the city, there are great cafes & shops nearby and it's easy to get a taxi on the corner. I highly recommend choosing this flat for your visit. You will not be disappointed.
