City Hotel Luxembourg was recently categorised with the “3 stars Superior” classification from the Hotelstars Union.
Hotelstars Union was created in 2009 under the aegis of HOTREC – the organisation that brings together all hotel, restaurant and café associations in Europe. Austria, Belgium, the Czech Republic, Denmark, Estonia, Germany, Greece, Hungary, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, the Netherlands, Sweden and Switzerland are members of the Stars Union family. Their partnership proposes a uniform classification of hotels, based on guidelines and criteria common to the participating countries. With greater transparency and security for the benefit of its customers, the union is working to extend the reputation and quality of the hotel industry in its member countries and thus consolidates hotel marketing.
