If you're a solo traveler looking for a quiet place to rest while you're in Paris, I'd recommend Alain's place. It's rather small and up four flights. But it has all the necessities and helpful information/maps. It's close to the Metro and right inside Montmartre, which is a nice little neighborhood. It's not close to the center of Paris, but that was sort of nice. And a taxi back wasn't much. The only thing was that Alain's friend who let me in only wanted to know when I was leaving. Not the best welcome to the flat or Paris.
