I stayed two nights here while in Luxembourg on business. This was much better than many hotels I have stayed at in the city and only a short walk from the train station.
The room was cosy and warm with a very comforable bed. The host had provided snacks, fresh fruit, maps and tourist information in the room. There is fast wifi. I felt very welcomed. The shower room was spotlessly clean and warm with a good shower.
I had everything I needed and my kind and hospitable host even provided me with a kettle so I could make myself a cup of tea in the morning (breakfast is not included). The apartment is on the top floor of an old building (which has a lift) and the room was very quiet.
I would definitely stay there again on future visits to Luxembourg.
