Travelled to Luxembourg with two friends, 3 people overall. The location is spectacular, very close to the main station as well as the city center. Just great. The room itself was alright, nothing fancy, generally clean. Towels were provided. No AC, so be aware of that in summer time. The beds were not very long, but if you are below 1.85m you should be fine!
BBassloThe room is big enough for us. There is a restaurant which serves food in room for 24 hours. The food was quite good too. It is just a 7-minute walk to the airport. If you have an early morning flight, it will be a great choice.
Unfortunately, the air-conditioner is not working very well. The room is quite hot.
