The appartment is very nice and location is the best in Lyon.
We haven't met Laëtitia personally, but she gave all the directions and information by email. The bad thing that we got info about the keys just 1 day before the check-in, however we made attempts to reach the host before the big trip (Laëtitia replied that usually she sends information 1 week before check in, probably we asked too early).
The apartment was cozy and clean. Amazing view from the windows. If you plan simply enjoy the city it is very good option to stay.
No wi-fi and TV (if it is critical to you, for us it was almost Ok). The host gave us an advice how to fix wi-fi, but it hasn't worked out…
Overall it was nice to stay in the Laëtitia's apartment, which is very unusual =)
