The hotel has a beautiful view over Luxembourg and the cocktail bar takes full advantage of them. Rooms are comfortable with water and soft drinks provided in the mini bar. The staff were lovely and friendly too. There is no free parking but there is a car park under the hotel which worked out at around 35 euros a day. We didn't have breakfast in the hotel - it was very expensive at 37 euros per person, but there are several lovely cafes and restaurants in town serving brunch/breakfast for half the price - we very much enjoyed Kostas cafe. All in all, a good place to stay in Luxembourg if you want comfort, views and warm, friendly staff.
The single room I booked was clean, but quite small and simple - I would even call it spartan. The staff was not very friendly; I would have expected a bit more. Still, I was not turned away :). The location is convenient, close to both the historical center and the European Quarter. I would stay there again, but without any high expectations.
The hotel overall was pretty good. The reception was very kind although the location wasn’t very ible if you don’t have a car but you need to remember that in Luxembourg all public transport are free to use. The only downside to the hotel is that they don’t have a mini refrigerator in rooms and you need to buy things and put in your mini refrigerator in the room so it is not recharged and it’s empty and for that you have to pay extra. overall, very good experience.
