Marion's apartment was exactly as described and couldn't have been more perfect - extremely cozy and quiet while being right in the center of Montmartre and super close to the Metro. There's also a gourmet ice cream shop literally next door that I will probably dream about for the rest of my life =) Marion was very responsive and her instructions for getting to the apartment and checking in were spot on!
Montmartre is an amazing neighborhood, and Marion's apartment was the perfect home base for exploring it. We would definitely stay here again!
