We stayed two inconsequtive nights at French Theory. We stayed in the same room both times. Getting to Luxemburg metro station was super easy, although we carried heavy luggage. The communication with the reception was quite easy, and they were very helpful, understanding and responsive.
In every corner, you could feel there have been a lot of care, passion and thought put into the redecoration of the hotel. We loved our room, particularly the gramofon streamer and the superb audio system.
