It's a very small studio with a cute little area outside in case you feel too trapped indoors. Matthieu left everything we needed as a start (coffee, soap, tea, basics for cooking and cleaning).
It's very quiet (until 10am when kids in the school take their break, then you hear screaming for a while).
I recommend to bring very little luggage if you are staying here because we had 2 small luggages and 3 backpacks and there was almost no space remaining for us to move and sit around. Which is why we spent most our time in the little terrace hearing music in a little speaker that Matthieu has in the Studio. Amazing touch!
Only issue (during winter and cold days) is the hot water for the shower. It's enough for only 1 person (or 2 if they really manage to take quick showers) but the idea for the studio is to host 1 person, that would be perfect and comfortable. For a couple... you have to be... a very united couple... or ask your partner to wait outside while you use the restroom because you basically poop in the kitchen/living room :)
Location is perfect. No problem at all. 2 metro stations and bus stops at 4min walk. In 30min you could be in the Louvre, for example.
