the studio is small but well decorated and well equipped. there is also a garden in the building, making it very calm and relaxing place although the location is in the very center of Paris. there is a big metro station nearby with a direct line to most of the touristic places. we (4 people) took uber as well which cost approximately the same as metro tickets. Rejane is super nice, she picked us up and showed us everything, replied to all the messages within minutes.
i would highly recommend this place, and defenitely come back when travelling to Paris.
