Location was perfect for my visit with family who live around the corner. Even better because the Luxembourg Gardens are a block away. Very comfortable apartment, 1st floor (for Americans this is 2nd floor), with stairs and elevator access. Kitchen, large bath with good shower (hard to find in 3-star hotels even), windows with shutters, walk-in closet... I was ready to move in! Clean (I think someone forget to leave toilet paper, soap or kleenex tissues, but I got them from family). Otherwise a great place, private, and will definitely stay here again in the future.
Communication with the owners' group was okay. My primary contact didn't respond after her initial greeting, so I got worried, but the leader of the group did respond and reassured me. Upon my arrival, I wasn't sure when I would have access, but contact person called within an hour to let me know the maid was finishing up and would meet me to provide the key. It all worked out and I have recommended this location to my family and all the friends that come to visit them in Paris. More comfortable and affordable than any hotel in the area.
