I stayed twice at this Novotel and it is a very standard French Novotel (which I dislike) and there is nothing to write home about. Never had any loyalty recognition apart the drink voucher. But I am quite surprised by your comment about room size. They are the standard Novotel room size with the bed and the sofa bed so they are quite large. Of course if you se the sofa bed as an extra bed, there’s no more room.
The only interest to stay there is if you go to a concert/show at the arenas.
