A nice, new hotel, comfortable, spacious enough (for your money) rooms with everything you need, including an iron with ironing board in the room (good Internet by default). The staff is very pleasant and friendly. Convenient location. It takes about 20 minutes to walk to Messe. To the central station on foot is about the same 15-20 minutes. There is no desire to walk, a bus goes directly from the central station in the direction of the hotel 37, the stop is literally at the entrance to the hotel (the bus runs quite often in both directions). An ideal stopover option for visiting the exhibition.
A decent hotel, clean rooms, friendly staff. A little away from the center, about an hour on foot along the embankment, 10 minutes by taxi (10-15 €). Breakfast does not spoil the variety, but quite to itself, the special joy of children is the device for making pancakes.
