All in all, I liked the studio. Although small and more adequate for one person, it was a recently renovated place and is very conveniently located, you can walk to many touristic spots of Paris. Daniele showed up on time as promised and she was available when I needed her. One thing which will make me hesitant whether to choose that place again when I go back to Paris is the neighbourhood, although not dangerous at all per se, cannot be described as "friendly".
There was a maintenance work going on at the corridor just outside the studio which made my entry into the studio a bit difficult, but it was not too uncomfortable.
