We highly recommend staying at Francoise's place. She was very accommodating with us arriving early in the day and checking out late in the afternoon. She gave us all the directions we needed to arrive from the airport ( 3 metros -1hr roughly). When you do arrive be aware that you will have to climb 3 stories of a narrow staircase. There is no lift.
The neighbourhood was amazing. Great bakeries, restaurants,bars and well connected to the metro. We were close enough to walk to notre dame(40min leisurely pace) but just far enough that we felt that we were in a real Parisian neighbourhood.
The place was well suited to our needs. The bed was big and comfy. The room had a nice sitting area and basic dishes and a kettle. The bathroom was all ours and really nice.
Francois was lovely. She checked us in and gave us a run down of things to do. Her English is not perfect but it was good enough for us.
We would highly recommend staying here. Great value.
