I highly recommend Catherine’s apartment. It was perfect for our family of four; it had all the amenities we needed, it was beautifully decorated, and the location was amazing, in the heat of the Marais, close to multiple metros/RER and a few blocks from the Centre Pompidou. Catherine was very responsive and kind, and the apartment was spotless. We stayed in august and I was worried about the lack of A/C particularly for the lofted beds, but even on the hotter days the fans in the apartment were sufficient and we slept well despite the heat. We will stay here again when we come back to Paris.
