“Paris is a village,” my Parisian friend Magdali always says. This is in reference to her opinion that Paris may seem like a large, cosmopolitan city, but it’s really a small town, which means word gets around. (You could view this as half full or half empty, depending on how you’re looking at the glass.) When it comes to Paris’s best-kept beauty and wellness secrets, the only way to know what’s worth your money and time is not through some vague Google search, but via word of mouth, from people who know the city.
