We were a group of 10 people travelling to Lyon. We wanted a place where we could all stay together so we found Alphonse's place on AirBnB. The communication prior to our arrival and check-in was very easy even though we all arrived at different times. The apartment has 7 bedrooms, each equipped with a double bed and 3 showers and 3 separate lavatories so there were enough for all of us. The sleeping rooms were small and the equipment simple but the apartment has everything you need to make your stay comfortable. A great plus is the large living room/kitchen, which is separated from the sleeping rooms. That way you can stay up and talk a little while others of your group may want to sleep undisturbed.
There are quite a few bars/restaurants near the apartment and the old part of the city as well as the river are well in walking distance.
I would definitely recommend this place for large groups looking for a place to stay in Lyon.
