The Ministry of Economy, in close collaboration with Horesca Luxembourg, proposes a formal hotel classification system, based on an initiative from the European hotel industry, called Hotelstars Union. This partnership proposes a standardised hotel classification, based on guidelines and criteria common to the participating countries. Through greater transparency and security for the benefit of customers, the union strives to extend the reputation and quality of the hotel industry of its member countries. The classification of an institution is voluntary. Each hotel has the choice to participate or not. In addition, the self-assessment tool available on the website www.classification.lu, makes it possible to become familiar with the required criteria. It can be used by any interested person and does not commit to anything until the validation of the request for classification by the user.
