I stayed this place with my parents for few days. and it wass really good.
It is located in an historical apartment but there is "an elevator".
There are plenty of towels and amenities that you might need during the stay.
And it was very spacious so I think 4-6 people could stay well.
The location is also good, walking distance to the train station, place Bellcour, etc.
And Sylvain is a verty good host. He gave me very quick responses to my questions and checked about my stay.
Overall, It was very pleasant stay and I highly recommend this place.
