Romain's apartment is right on the square where Picasso once lived in Montmarte, and the apartment has a lovely little balcony (only big enough to stand) that looks onto a cobbled staircase going up the Montmarte with old-fashioned streetlights. Herbs are growing in window boxes outside the kitchen, and unlike many Airbnbs in Paris that are run by companies, this one has a personal touch as Romain actually has insight into the neighborhood and provided restaurant and other recommendations. WiFi was good, the apartment is only a 5-minute walk from the subway, and Romain was really flexible and available. No one was coming into the apartment the day I was leaving, and he let me check out late, which I really appreciated. He was also flexible about meeting me early on the day of check-in. I wouldn't recommend this place to anyone with mobility issues because you do need to walk up a big hill to get to the apartment, which would be difficult for those unable to walk far/easily. In addition, you need to climb into the bathtub, which is also the shower, and there isn't a curtain, which could be challenging for some. Make sure you check out the bakery Pain Pain and the wine shop/wine bar in Roman's book, which is the best I encountered in Paris.
