I would not return nor would we have stayed except that it was already paid for and late in the day to look for another place. We were even tempted to leave Lyon altogether and continue our travels and throw away the cost of the room. Instead we opted to stay away from the room from 8am to 10pm just so we wouldn't have to be there longer than we needed to sleep. We were misrepresented by the profile: superhosts?, "big" kitchen, living room with a balcony (we never saw), and 2 "cool" cats that made the entire apartment stink and the floors so filthy I rather keep my shoes on.
Good news: location - very easy to Metro and one stop away from Vieux Lyon, the host's mom is super sweet, and the bedroom itself and sheets were clean.
