I plenty recommend this apartment: our stay was really comfortable and easy to get there.
There is a metro station (2min by walk and 2 metro lines, easy!! but don't be lazy, the city center is just 20min away by walk!!) also some bars/resto and supermarkets around the apartment. The metro station link the apartment to the city center, Bellecour, and the main train station, Part-Dieu.
The apartment is really useful and big enough for a couple and has several details that makes it confortable, for instance, the shower is big and modern and the decor of the wall is funny! Also the kitchen that is quite complete.
About Emilie, she is always available via email and we always had a quick response but what we really apreciated was to don't need any direct contact with her to get the keys so you are free to arrive at any time. Emili also sent us a message about what to do and where to eat during our stay in Lyon.
