The apartment is located in Vieux Lyon, the old town of Lyon, which in itself is very nice and lively but is also close to the central districts of the city (lots of sightseeing or hip spots can be reached within 30 minutes by foot).
The apartment is stylish, clean and well-furnished. Some people mentioned the ceiling is quite low, which I can confirm. I'm 186cm tall and it was a bit of a challenge to walk around, however, I hit my head only twice which I consider a win. At the end of the day, the place has all you need for the stay and you're hopefully spending most of the time outside anyway.
Some people also mentioned noise coming from outside. Yes, there's a jazz bar right outside, opposite the windows, there's also a restaurant right below the apartment, so you can hear people talking and having fun late in the evening. But hey, you don't know French anyway, so it's just a "background noise". Plus, with the windows closed, you can't hear anything in the bedroom, so no trouble sleeping.
I'd definitely rent the apartment again.
