I stayed in the studio for four months during my Erasmus semster and really enjoyed my stay. The apartment is perfectly located to explore Lyon. Croix Rousse, Hotel de Ville and Vieux Lyon is within walking distance. Apart from that the bus stop is just in front of the door. The area is very quiet and I also felt safe when coming home late.
The apartment is very well equipped: lots of lights, hairdryer, etc. only some of the kitchen equipment should be renewed.
I would definitely recommend the studio for a longer but also for a shorter stay.
