I stayed several months at the hotel and would not recommend it.

Pros:
+ Central location (near station)
+ Price relatively modest by Luxembourg standards

Contras:
- Dark rooms (not enough lamps)
- Noisy (both from within and outside hotel)
- Rooms smell (not very bad, but still annoying)
- Smoke from neighbor's room spreads out on whole floor
- No own reception service (only at partner hotel Christophe Colomb)
- Moody and on two occasions even outright insolent service more
