Very cosy flat in the city center. The studio has everything you need to enjoy your stay and the view on the mountains is very nice. Augustin is reactive and does care about his guest' comfort. I highly recommend this place if you're visiting Geneva.
Be aware that the Cathedral's bells ring every 15 minutes. It was not a problem for me but it can be if you're a light sleeper. Except of that, the area is very quiet.
