The apartment is really well located in the city center and close to everything (metro station 5min away, shops, cafés, restaurants around the corner...).
It is a nice little flat, maybe more suited for a couple or close friends though (as there is no real door in the bathroom but a curtain). The kitchen was well equipped. The toilet may not be confortable for tall people as it is rather small, but we had no problem with it.
It was really hot in Lyon the time we stayed there with my friend but Christel provided a fan that we enjoy during the night! The street gets a bit a too noisy to keep the windows open early in the morning (small street and garbage trucks are early birds!).
I would recommend this place!
