I found Rose-Marie's studio lovely.
The decor is all-over the place (with an impressive collection of things lying around), but definitely not boring.
All the amenities work (wifi, kitchen appliances, etc..) and is very near to the metro.
The only thing that takes away from it's greatness for me, is that with such a big collection of things in exposition, there is bound to be a bit of dust (and there was). Also, the mezzanine may feel slightly claustrophobic for those who like a lot of space between their heads and the ceiling. I couldn't quite sit upright on the bed.
