The impressive price was due to some repair works going on near the room. To be fair, they only started around midday, though after watching France-Iceland in the fanzone I would've still wanted to sleep a bit more ;)
My flight home was cancelled due to the French strikes, but fortunately it was possible to extend my stay for one day. However, I was only flying at 6am the next day. I stayed in the lounge for a short while, but then wasn't allowed to. I understand that, but I also wasn't allowed to keep my luggage there anymore "because I didn't have a room at the hotel", although the purpose of the luggage room is literally to keep your luggage between midday and your departure. It wasn't even 24 hours. The staff was fairly rude about it Also, the breakfast is really expensive if you pay for it separately, but it's really good, probably the best I've seen in France.
