You need to be ready of no elevator and since it's a huge castle, you might get the room far away from the entrance, so...it might be really painful when carrying your luggage up and down, left to right~
When I booked the hotel, I planned it only a place for an overnight sleep, expecting nothing more. But when we arrived in this 12th century castle, we were more than surprised to find a lot of perfect things, like the great location right next to the Lake Geneva with direct open view, great history, interesting floor plan and decorations, etc. And the staffs are really friendly and helpful, who direct us to the 2 floor with luggage taking as well. A sure to come back place.
