About the Appartment :
It's one (if not THE) best thought about airbnb appartment we saw, and many times we said we wouldn't mind living in it. It's perfect for short but also longer stays as there is a small kitchen and the hosts are providing a lot of stuff to cook in (pan, cooking knife, board, peeler...). It's very clear that this airbnb is completely new and was done with "comfort in mind" and it shows :)
Location is not that far from the Train station (easily walked there) and there are groceries + good food nearby. It's also walking distance from the Lyon basilica :)
About the hosts :
The hosts had a VERY VERY positive communication with us, and even trying their best to accommodate our requests and questions.
Don't hesitate, just go for it :)
