The place is really small. Two persons with backpacks can not turn around. What you see in the pictures is all you get. There is almost no Network in there (sometimes on the couch and always on the window).
The room is not as decorated as in the photos (the second image of the couch applies) which makes it not as comfy as expected but the host is really nice and also has recommendations on where to eat or go out.
The location could not be better. You have really good public transport nearby and also a lot of POI in 15 minutes by foot (Louvre, Garden of Palais Royal, etc).
