Nicolas' place is affordable and straightforward. You will just be housesitting for him, but this was enough for our needs in Lyon for the short time we stayed. The metro station was only 5 minutes away, and Lyon Part Dieu was 15 minutes away, by walking. From the metro, we were able to explore Vieux Lyon, easily get to Perrache station, and visit most of the busier places of Lyon.
When at home, the balcony provided a nice breeze and a nice open view of the neighborhood. There is every basic necessity you might need, and for the price, provided everything we needed.
