I only stayed at Francoise’s place for one night, but it was a pleasure! The communication was very good (except for my horrible French), the Arrondissement is very vivid and I was able to leave my luggage at Francoise’s while visiting the Louvre (although I was already checked out). The room is small, but very cozy and Francoise and her daughter left me a lot of privacy. The kitchen and bathroom are shared.
I would definitely recommend a stay! :-)
