It's an entry level model from the bike boom era 1970-1974. It looks it has "nutted" hubs - hex nuts instead of wing nuts or quick releases.

One recommendation: always post pictures of the drive side of a bike - the scary, dirty, ugly stuff that makes it go. They're some of the most important features for identifying a bike. Also closeups of the areas circled in the picture below.

The city of St Etienne was the capitol of bicycle manufacturing in France. St Etienne brand was mid-range marque.

The few that I saw during the early 70's were all entry level models with decals that looked a lot like those used by Gitane.

The bike looks like it's in nice shape.
