One of the best places I have stayed at (and I have been to many Airbnbs!)
While the building itself is super old (1600s!), the flat was recently rennovated with taste, and of course, a dazzling French touch. All the furniture was lush and very comfortable, especially the bed.
It is located in the beautiful old Lyon, with the advantage of being super quiet and calm. I was never disturbed from the street, and slept splendidly.
Last but not least, the shower was glorious, kudos to whom ever built it.
One thing to notice however, is that I would not recommend this for people with limited mobility, as the old staircase can be quite slippery, and are difficult to climb. Also, while the flat is extremely quiet, you do need to always have the lights on as its quite dark.
