I recently went on a business trip that included stops in 7 European cities. This hotel was easily the best I stayed in during the whole trip. For 4 nights I had a comfort(double room) with breakfast buffet included. The room was very large, much larger than most hotels I've ever stayed in. Besides the 2 beds there was a sofa and plenty of space left. There was even a separate, quite large, dressing room !!
The breakfast buffet is amazing and actually worth the 15 Euros that you have to pay if it is not included in the room price. It is very diverse, and they have even raw salmon and eggs with caviar. In the afternoon they also provide cakes and drinks for free in the eating area at the top floor.
Some other random pieces of information. I used their service for ironing shirts. Very cheap compared to other hotels in Europe and the quality was decent. The staff was very polite and spoke English perfectly. There were some problems with the wireless Internet but got solved after a few hours. I would definitely come back.
