Great neighborhood. Safe yet lively. The nearest train station is currently under construction, but it's still a short walk to the next one over. It's an area with its fair share of immigrants, and a bit of a hipster/art/nightlife vibe, so you get a lot of local flavor, and many different types of cuisines, at varying price points. Beware of the typical French restaurants and bakeries in this area though. Since it's so close to Sacré-Cœur, some can be a tourist trap. Definitely ask Pierre for restaurant recommendations in the area, as the ones he gave us were wonderful. Most importantly, the apartment is clean and cleverly arranged for such a typically Parisian sized space, and the bed is comfortable, and there's a very handy electric heater to keep you warm at night. It's also easy to access other notable parts of Paris by metro, or if your feet are feeling adventurous, by walking.
