We absolutely loved our stay in Armelle's apartment. We were there for an extended stay (more than 1 week) and couldn't have imagined a cozier, better-located spot to live in Paris. There's also a very cute dog who lives across the street and pokes his head out the window to look at passers-by :)
I will note that as a medium-tall person (5'10", or 177cm), I was not able to fully stand up in the loft bedroom, though my partner (5'2" or 158cm) had no trouble. It had literally zero effect on the quality of our stay, but wanted to flag that it might make a difference for taller travelers!
