A good hotel for the duration of the exhibition, we often stay here. The price is only charged per night during the exhibition, but the location is convenient, the rooms are 2 times larger than in typical German 3 and 4 rooms, the restaurant and breakfasts are on the level!
I can't name a more convenient location of the hotel in Cologne. The cathedral, the train station, the pedestrian zone, the embankment - all this is around the hotel
