My fiancee and I stayed at Hayann's apartment for 7 days and found it to be cosy, functional and well located just outside of the Vieux Lyon area. Hayann greeted us and was extremely helpful and welcoming, giving us an overview of Lyon with recommendations for places to visit and restaurants to eat at.
The apartment itself is small, but has everything you need for your stay, with a well equipped kitchen, bathroom and living room. The bedroom is on the mezzanine level which provides a cosy, comfortable place to sleep.
I would definitely recommend staying at Hayann's apartment and would do so myself again in the future.
