The hotel was full, so no upgrade this time. Although from the window I could see the castle, so I'm not really sure. That's just what they told me at reception. The room was unbearably hot, so I asked to change rooms, but the other one was exactly the same. A technician came to check it and measured 32°C in the room. As compensation, I got free access to the wellness area, which used to be complimentary but isn't anymore, even for VIP guests.
