Marie’s apartment is beautiful and spacious for 4 people. It is clean and no stairs to get in, it is a first floor/ground floor.
Location is amazing, Sacré-Cœur is right next to the apartment. Lines 4 and 2 of the metro are 5 minutes away walking. It is very easy to move around to other parts of the city.
I wish I had stayed there my whole time in Paris.
