It's a room in a house where many people live together and share a lot in common (like good time, bathroom, living room, kitchen, garden). Need to be respectful to the others. 25 min by metro to Chatelet. Many shops/restaurants/transports around.
We are easy-going, easy-to-share, respectful.
And we expect you to be tolerant, not noisy, especially at night, and to respect the security rules.
