I read quite a few in my early teens, and it did evoke an image of Paris back in the day. So much, that at first it was a bit inconsistent, confusing, until it turned out that I was reading them in random order, and some were decades apart. One detail that has stuck was the presence of a stove in Maigret's office: in some books, he pokes the thing continuously (or so I remember), in others there's central heating. Because the books set in all seasons, many of them don't even mention heating, which makes it even more mystifying.
