Yannick's apartments was great. Sacre Ceour is walking distance (5-7 minutes), the views from there are unforgettable. There are also a lot of great little wine places and restaurants. The apartment itself was very clean, cozy, and it has a place to cook. It is within 5-10 minute walking distance to a metro station, so getting to the city center was very easy. Yannick was very responsive during the stay. We would definitely recommend staying there.
