Charline's place is conveniently located very close to a metro stop and Gare du Nord (10 - 15 minutes by walking). The accommodation is located in a building that's also part of some type of market? It seems to be quite lively during the day, however, it quiets down at night after the front gate is locked. I didn't feel unsafe in the neighborhood, but I was definitely more cautious than normal while walking through it at night. Charline is very communicative and responsive to messages. She is also very accommodating with my concerns and needs. I enjoyed meeting the other travelers from different parts of the world since I shared the room with 5 others. I also enjoyed meeting Charline's mom, who was also very generous and caring. I would recommend this place for its location and price, especially if you only need somewhere to sleep while exploring Paris.
