I would 100% recommend staying at Mathilde’s. She is wonderful - very hospitable, caring and responsive. Her taste and knowledge about French cuisine and food in general are incredible. The room is just as advertised, clean and close to the metro (2 min walk) and the Tour Eiffel (25 min walk). Nearly all the tourist attractions are within 30 min distance by metro. The neighbourhood is safe. I would love to stay at her place again if I visit Paris again in the future.
