We had a lovely time in Lyon for the Euros! The apartment was a nice space with a cool balcony though it did get a bit warm as it was summer (though as a Brit I'm not used to hot weather!) and the stairs up to the top floor to reach the flat can be a challenge with heavy bags! The flat is near a metro which is very helpful.
I never got to meet Elise and Julien unfortunately but they were very helpful beforehand, arranging to meet my brother who was arriving earlier to pick up the keys from them.
I would definitely recommend anyone to stay at their place.
