Katia and Thomas are very nice hosts, you can almost instantly expect a response from them if you have any questions. The check-in instructions were clear and easy to follow. The apartment itself is very clean and has everything you need, but be aware that there are no windows. Furthermore, the apartment is located on the ground floor at the courtyard, right next to the back entrance of a restaurant where the employees sometimes come out to take a break. We never had any trouble with that, in fact we even had a friendly conversation with them. All in all, the apartment is perfect for visitors who prefer to explore Paris the whole day and just come in for a good night sleep.
