Yann was a great host: nice, attentive, thoughtful and helpful at all times. The flat was super cozy and had everything one can need when traveling; it is also in a perfect location, very close to a metro station and right next to Sacré-Cœur. We had a great stay and would totally recommend it. We would definitely go back to Yann's apartment if we go back to Paris. It was a wonderful experience!
