Mathieu's apartment is very lovely. My husband and I stayed with our 9 month old baby. He set up a pack n play for us in one of the rooms and it was great to have a separate area for her. The bathrooms are nice and modern, which is not common for Paris! The kitchen is well equipped with a washer/dryer machine and anything one might need. My only complaint is that while the location is nice, it is a bit too far to walk into central paris. It was easy enough to take a subway or uber and only took about 10 minutes to get to central left bank, but not as easy as walking out and being close to the main sights. I knew the location when booking but hoped it would be a bit more central.
