This apartment was clean, lovely, not too small, and in an excellent location for getting around Paris. The hosts were wonderful and left the fridge stocked with waters and milk for our coffee, plus some fresh fruit. A very nice touch. It is on the 4th floor, so be prepared for the five stories of stairs (for those in the US the French method is ground floor is 0, then 1, 2, etc.) but the housekeeper generously carried my wife's heavy bag up for her while I carried my daughter's and my own bag. The windows opened easily and we were able to get a good cool breeze through the apartment, and since we usually sleep with a fan, the light traffic noise was a plus for us. With the windows closed, the space was quiet, and we heard nothing from the other apartments above and below us.
My wife is generally much pickier about AirBnb and hotels (we've changed rooms at hotels several times on a couple of occasions), but even she said that she would come back to this one.
