It was great to stay in this place. It is tiny but it has everything necessary to spend the weekend in the city. The location is nice, with easy access to metro, Gare du Nord and Sacre Coer. There is a market on Sundays just next to it.
The only note (that I did not check before) is that there is no wifi.
But overall, we had a great experience with Pauline and she is very responsive and nice! Would stay again, many thanks.
