I stayed 2 nights on business. My room was very spacious and clean. Great location. The no1 tram from the train station stops outside. It's only a few minutes walk into the beautiful old centre. The other Ibis is outside the cathedral and charges significantly more for the location.
The buffet breakfast was good, but the breakfast area was very busy. Unfortunately, there was a lot of corridor noise one night and my sleep was disturbed. My only other complaint is that on arrival at the hotel, it took ages to check in.
