I had a great stay at Jean-Charles's place.
He was very communicative and easy to reach and the place was beautiful. Even though it's in a busy area it was very quiet and peaceful. The space is lovely and was very clean and comfortable. They even have a lift in the building which is nice when transporting luggage and such.
The location can't be beat. Right in the middle of a restaurant/bar area, 5 minute walk to Metro and 5 minute walk over the bridge to the old town.
Would absolutely stay here again when visiting Lyon.
