The apartment is beautiful and more than enough for a couple. Stylish and well equipped, and Céline was a lovely host and very responsive.
There are metro stations 3 minutes walk from the flat and 2 Franprix (supermarkets) as well. You can walk to Sacre Coeur, Montmartre, Pigalle and feel like a local :)
Definitely coming back to Céline's flat, we felt so much at home!
