PRO: gorgeous flat, everything it's here including tons of board games and even a nice pianola. Astonishing check-in: clear explaining of how the house works, plus a manual made by the host with all the informations you need including public transport, restaurants, bar ecc. Nice location, astonishing church near the flat, many supermarkets and bistrot plus many metro (underground) stations at no more than 3-5 minutes from the house.
CONS: none of the room have a proper chandelier, most of the illumination system needs to be plugged and we had problem to understand how to do that in the kid room. No conditioned air and the flat gets hot really quickly. Also a little bit too much communist propaganda spread through the flat for my personal taste.
Bonus cons for Italian: no bidet, but I suppose that's common in France.
Will I recommend it? Absolutely yes. Without any doubt yes. Can't image a better solution in Paris: awesome price for a super-awesome flat.
PS the kiddo has a nice Pokemon and Warhammer collection, thumbs up 👍🏻👍🏻
