We stayed 1 month a Louis appartment. We have been the two of us, but you can easily be a family / group of four. It is indeed a great place where we would always go back without hesitation when spending again some time a Lyon ! I can highly recommend.
What makes it so special ?
The place - you are finding yourself right in the city centre and yet it is calme
The appartment - It is a spacious place, sunny, well equipped, all equipment is functional and working,
The host - Louis helped us with the check-in and was always quickly responding when we had a question.
Note that you are on the 4th floor.
