Never come to Brussels when there is a seafood conference. The cheapest room I got at 7:30 pm was 250 Euros, without breakfast of course. Outside it was raining cats and dogs, pretty cold, so unfortunately there was no other way.
The guy from the reception even apologized to me. Sorry, he said but we are already like the airlines, when there are only a few rooms left, our hotel computer automatically increases the price. You can look somewhere else but it will be difficult to find something cheaper anywhere.
