I spent 4 nights with my family and friends in the beginning of December 2021. There were 8 of us and the apartment perfectly fit (for a few days). 4 rooms, fully equipped kitchen, 2 bathrooms (maybe these last ones a little small, but the showers are regular size). It is located near Poissonière metro station, so moving around is really easy.
If I ever need again a large apartment, I’m sure I’d take this one more time.
