I do not know where to start.
Upon check-in I asked for a calm room. Despite this, I got a room facing the motorway. Although other rooms of the same category were available, staff did not want to help me with my request to change the room.
In line with that, the statement of the hotel that they would have well isolated windows is a false statement. Being in my room having the windows closed, one can hear traffic very clearly.
While the room was supposed to have a bathtub, it had a shower with no curtain or glass wall or anything. When taking a shower, the room was usually completely flooded since the floor was missing a slope to the drain.
Upon check-in I was handed a card that stated the times of breakfast. For no understandable reason, the real times differed significantly (breakfast served until 10am instead of 11:30am) from the times that were handed to me.
Furthermore, I completely dislike that a four star hotel (self-) serves coffee and juices at breakfast exclusively in disposable cups.
At the event I participated, I recognized that staff closed and locked emergency exit doors which I consider absolutely not acceptable when having >200 people in a souterrain room.
Also, one of the elevators repetetively went out of service, which seems a minor issue as compared to the issues mentioned above.
The surroundings of the hotel are not very pedestrian friendly. When approaching the hotel from the train station, muddy path.
Never again for me.
Cannot recommend.
