Very nice location! Cozy neighborhood with restaurants, ice cream 20m from the entrance door and close to metro stations and tourist bus stops if needed - what we used due to train / metro strikes. Space ok for 3-4. Good sofa bed. Ignore the white metal box at the door entrance and focus on the code box only and make sure you are ok climbing 3 floors on a narrow stairway. If ok, then you have a very good appartment to be at the heart of Paris!
