Great location is the main thing! If you find yourself in Lyon in these beautiful old quarters you actually do not care a lot about the details of the apartment you are living in since you normally return there only to sleep. That said, it's a quiet place,
fully-equipped and comfortable enough (for this moderate price). The only serious thing for us was the of lack of fresh air in the entresol (where the guests sleep), even with all the windows opened. Probably when the temperature outside is lower than +34 it does not matter that much ;)
