Floriane's place is modern, newly renovated, thoughtfully designed, clean and very well-equipped. I stayed for four nights and thoroughly enjoyed my time. The apartment has great amenities, from coffee & tea to washer and dryer if needed, the bed is comfortable, the shower has great water temperature + pressure.
Neighborhood: The apartment is in a nice neighborhood by the Republique: lots of fun restaurants and cafes close by, highly walkable. The street is quiet.
The building: There is no elevators - as is usual in Paris - so be prepared to take your luggage upstairs. The apartment is located on the 2nd floor. Floriane might also be able to help you store your luggage if you give her a heads up.
The host: Floriane was super responsive, friendly and helpful.
All in all, a great experience staying with Floriane! I'd highly recommend her apartment.
