The room (on the 7th floor was too warm. We couldn't put the heating off because it was in the floor. We asked it at the reception, and they told us to put on the airconditioning or open a window.
During our entire stay, the window was open and the airconditioning on. Personally, I still don't understand why it isn't possible for you to turn the heating off, or lessen it. I can imagine you have quite big energy expenses.
This is the only remark I have, all over I am very happy about my stay.
