Excellent budget hotel near the airport. There are free buses to the center of Luxembourg. 15-20 minutes - and you are in the center. It is very convenient to take a walk when there are several hours before the flight.
The breakfast is simple but hearty. I recommend.
A good place for a temporary stay on the road, the rooms have everything you need, but you will have to ask for an iron separately. As the description in the bathroom says, "you can not be afraid to drink tap water" and it's true, the water is of excellent quality in Luxembourg. Of course, the staff speaks English.
I didn't like the hotel. No, everything is clear, he is not there to stay for a long time, and we stayed for 1 night in total. But there was a terrible smell of cats in the room and on the floor. This is critical for me. Otherwise... a small room, a tiny shower, a washbasin separated from the "room" by a curtain... Breakfast is ordinary - bread, some muffins, cheese, yoghurts, bread spreads, a couple of cuts of something meat, boiled eggs, apples, tea \ coffee \ water.
