Although we never met Laurent in person (he was always in tough online), we were welcomed with a lovely lady, who showed us around and was available for further questions. The apartment is lovely, very clean and has everything you might need. Location is close to perfect, with a stone throw to two metro lines and bust stops. Since we stayed in December, heaters worked properly, and we never experienced troubles with hot water or wi-fi connection. The only minor disadvantage was the absence of lift (so typical of Paris), and the stairwell was pretty narrow, so if you have really large suitcases, you might not wanna go that far. Otherwise, the apartment is lovely and strictly recommended.
