Audrey's studio is great! Cozy and homey and with everything you could need.
My greatest concern was probably having to share a toilet, but I never had an issue with someone else using it when I need to.
The place is *so* tiny, so do be aware of that. It has some tight spaces, too. I'm a relatively slim 5'6" woman and wondered how anyone much bigger than me would navigate the space.
I liked the neighborhood here more than any other place I visited in Paris! But be forewarned, it's really quite hilly. You'll definitely get your calfs a workout.
And make sure you check the RATP website for up-to-date info on the Metro! While I was there, the Marcadet-Poissoniers (the closest stop for the 4) subway stop was closed, and that *really* threw me off as I was coming into the city for the first time.
