I stayed in Francoises apartment for barely four months. I absolutely loved the 14th, and especially that part, as it was quiet, yet full of locals.
The apartment was placed within the backyard of the building and was therefor free from traffic noice. It had all the necessities.
My only struggle was the bathtub/shower as the old paint was chipping away making it uninviting to sit in. Without a shower curtain it was quite easy to spray water in places it is not supposed to go.
