Walking into the room, I was like "yuck," and thought this would be a cheap crappy hotel. I rarely stay in hotels. Anyway, later my opinion changed. Sheets, pillows, etc all very clean, bed was very comfortable. Be careful of staying there if it'll be hot in Grenoble. Windows open, but very hot in room. We were lucky it was only hot our last night. They give you a fan, but it has very little power so basically does nothing.
The staff there were great and SUPER helpful, also improving my opinion of this place.
