Hotel was located close to the central station. The room was spacious and quiet, the bed was comfortable. Cannot recommend the views since only we could see was the inner court. Generally, hotel staff was friendly.
The room had muddy, cellar like odor. If one has asthma or is sensitive to mould, I'd consider this hotel twice.
Then, for being a 5-star hotel I consider the following things as downside and here Amrath really did not meet my expectations. Hotel staff did charge the room twice. They refunded the latter case quite soon after I noted about it. Also they do make a 75 eur reservation per night, just in case something gets broken. However, they did not mention that before I asked (again) why my credit card was being charged. I got the answer yes but why didn't they mention about it during check in.
Finally, a mention about the breakfast. For a cost of nearly 30eur per person I was expecting more. The selection was rather typical, nothing fancy there. No one assisted you to the tables nor offered coffee or tea. It was like any other typical tourist hotel. I've got much better service in many other lower rated hotel. So, might be a good option not to prepay for the breakfast for every single day but try it once and see if offers value for the money.
