We visited Lyon during the Festival of Lights and were totally overwhelmed. The installations were beautiful, the people no matter how cold it got during the nights and how crowded, they kept their good temper. As for Boris and his flat - perfect location, everything was in walking distance. We had the green room and it was absolutely sufficient for two people eager to see the city more than chillin' all the time inside. I can confirm the billion-stairs, but one also gets used to it. I can also confirm the cat, which is adorable and a total plus to the rest of the package! To sum it up - we can recommend his flat, the city, the cat and had a wonderful weekend in Lyon!
