Francois' place is the real deal - a true AirBnB. You're staying in his apartment (complete with his clothes and personal belongings) and it's magnificent. Very large, well proportioned with all the amenities you need for a great trip (even including an oyster shucker that we put to good use after the Sunday market at Bastille).
He's a great host as well, providing little welcoming touches of cake and wine to make us feel at home, a list of tips on the neighborhood and regular check-ins to make sure that everything is OK.
The place itself is very spacious, especially the living room. Possibly better suited to a family than 3 adults (which is what we were) but only because the beds in the "children's" room were pretty small. Wasn't an issue for us but could be for some. Next time you're visiting Paris, if you're lucky enough that Francois place is available don't hesitate to book it.
