We stayed in this hotel for two nights which we booked with a gift cheque (which had several locations to chose from).
The hotel is very nice, modernly furnished, and well looked after. Admittedly, you see that it is one of the many hotels of a hotel chain,n but we did not find it disturbing. The room we got was not large, but still large enough. We did not have the intention to spend much time in our room after all. Breakfast buffet has a wide variety of choices, including quite a lot of local specialities. The staff was really caring (offering extra items) and constantly kept the breakfast room clean (cleaning up tables immediately when people left).
The hotel is centrally located in the city. All interesting places are within walking distance. We parked in the hotel garage, but I think there is enough free parking space in the city within walking distance of the hotel. So, you could save some money on that. Although we booked two nights in the hotel, we found it hard to spend three days in the city, so the last day we visited Luxemburg city. There are also some nice gardens in the surroundings from Nancy, which we did not visit but which seemed nice (judging from a brochure we got).
