I stayed 2 days at Jeanne's place. Her place was amazing, and the room was cozy and clean. Her house is located in 20E, but it was not difficult at all to go to places like Le Marais or the center of Paris by metro/bus. She was generous enough to provide all the information I needed such as good breakfast/dining places in the neighborhood. I would love to stay at Jeanne's place next time I visit Paris.
