This is an amazing location in Lyon - right in the center of everything. My wife and I arrived during a World Cup game (France won!) and the entire street was packed with fans. We had to watch the end of the game before we could even get to the apartment.
The apartment itself is very nice and felt spacious despite the square footage. Be careful going up the loft stairs (we both hit our head a few times), but the bed is nice and comfortable and there are extra pillows in the futon.
The air conditioner / fan (not sure the proper name) downstairs is nice, but we did need to use the fan in the bed (although this was mid July). The windows insulated the noise very well (we kept them open one night and closed the next so could tell the difference).
We ate 2 meals right around the corner, but also walked around the neighborhood and shopped and visited various landmarks.
If you are traveling to Lyon for pleasure, Damien and his apartment are a great choice!
