Overall a great place to stay, as long as one's mobility is compatible with the sleeping arrangements.
The location is superb, with most of the things you want to see in Lyon within walking distance.
The apartment is nicely modernised retaining old character with a nice shower room, good shower and nice kitchen area.
The WiFi is very fast and the TV facility includes an embedded Chromecast which was useful for me.
The sleeping arrangements are interesting as the double bed is up a steep set of steps, so not accessible to anyone with limited mobility, and a bit of care needed when needing the toilet in the night.
The sofa bed is extremely comfortable and is folded and unfolded in seconds without the need to remove the bottom sheet.
The lift worked well, so we didn't need to use the stairs, but did try them and found them rather dark outside of daylight hours.
