I visit Lyon often and this was my first disappointing Airbnb. It is a nice apartment, however as others have stated, it is small and the narrow stairs to the 4th floor can be a challenge. They are spiral, old and tight. The Royal Indien restaurant is on the first floor so be prepared for the cooking smells.
I encountered some issues checking in and lost communication with the host a few times (they were on holiday). Don’t get me wrong, it is a nice apartment in a great location with all the amenities advertised but the TV did not work. The host did provide a workaround for the Wi-Fi. I would only recommend staying here for the historic/nostalgia value of the apartment. Otherwise there are much better Airbnb rentals for the money.
