Excellent location to explore Lyon, specially if you enjoy walking. It's a tiny studio but it has everything a traveller would need, including free coffee and snacks! :) ( there are great coffee shops close by if you want more).
As others mentioned, it's very load at night (from time to time) so bring earplugs.
Yann is a great host and I'm glad we eneded up airbnbing his place for our first visit to Lyon. Highly recommended.
