I went to Lyon for a fellowship in September. I needed a place that I could spend the month with comfort and easy access to work and to the city highlights. That's exactly what I got! Celine's flat is super clean, well furnished and had all I needed to spend the month feeling like home. Metro/bus/tram stations are near, but you can easily walk to the park, the river, the old city... Communication was very friendly and quick. I had a few "everyday issues" with the house (leaking sink, power cut down) that were really out of host's control and were promptly solved in it's best way. I really appreciated that.
Celine is very kind and available, great hospitality. I had the nicest reception and found some basics supplies for the first day. Great tips for restaurants, bars.
I definitely recommend her place for a long or short stay. You won't regret! And I would love to come back.
