Spent 1 night in Paris and the 3 of us stayed comfortably in Marie's apartment (one on the bed, one on the pull-out sofa bed, and the other on the 2nd sofa which is long enough for an adult). Self check-in, ground level, and clean apartment. About a 13-15 minute walk from Gare du Nord but if you're rolling suitcases, be prepared for small sidewalks. Marie is quick to provide information and respond to questions. Super helpful and kind host.
