Luc was a fantastic host! His knowledge of neighborhood was very insightful and he made every effort to make us feel at home in his home.
I know some past guests complained about the location, but we thought it was great. Away from the high tourist areas but just close enough to some of the action, and a more Parisian experience. With a couple options for Metro lines, it was easy to get to different parts of the city with fewer transfers. And the walk brought us by things we might not have ever seen, such as the beautiful cemetery, neighborhood cafés, bars, and stores. His place is also an easy walk to Moulin Rouge, Sacré-Cœur, and other popular sites.
Our biggest complaint is the street noise, so bring earplugs! The one-lane sidestreet is deceivingly noisy. With an uphill climb in the direction of traffic, we heard all the scooter, car and truck engines. And being only one story up (great compared to the many other 2+-story walkups), we could also hear pedestrians. This is no fault of Luc's, but just a heads-up for any light sleepers. Of course, shutting the window was an option but it was warm at night there would be no fresh air.
We never actually realized Luc is a smoker, but that might explain the mild odor in the apartment. We're a bit more sensitive to smells as we're not smokers ourselves, but for anyone not bothered by new smells and sounds, Luc's place is great.
