Had a great stay in Lyon, the apartment is in a great location outside of the old city but right near a metro stop and a few short stops away (<10m). Easy to get to any neighborhood, train stations, etc. on the metro. I walked home a number of days via different routes which was very nice if you enjoy walking. It's right by a fairly big organic grocery store.
The studio is spacious in the main area. The loft area was shorter than I anticipated - I could not sit up in bed for example, but was fine for my 5-day stay.
Check in was easy, Sébastien was super responsive.
One note: Google maps does not seem to have Lyon's transit information. It will always recommend you to take a mainline train, walk, or take a taxi even when something is one or two fast metro stops away. Download the TCL app to get proper transit info. The Lyon metro is fast, cheap, clean, and easy. Runs very frequently (every 2-5 minutes).
