Facilities are deemed "world class in every manner" and services are deemed meticulous and "exceeding all guests' expectations". </Td> </Tr> <P> The HOTREC (Hotels, Restaurants & Cafés in Europe) is an umbrella organization for 39 associations from 24 European countries . At a conference in Bergen in 2004, the partners drafted a hotel classification system in order to harmonize their national standards . In 2007 HOTREC launched the European Hospitality Quality scheme (EHQ) which has since accredited the existing national inspection bodies for hotel rating . </P> <P> Under the patronage of HOTREC, the hotel associations of Austria, Czech Republic, Germany, Hungary, Netherlands, Sweden and Switzerland created the Hotelstars Union . On 14 September 2009, the Hotelstars Union classification system was established at a conference in Prague . This system became effective in these countries in January 2010, with the exception of Hungary, Switzerland and the Netherlands, who have chosen later dates for the change . Later more countries have joined the HOTREC hotelstars system: Estonia (2011), Latvia (2011), Lithuania (2011), Luxembourg (2011), Malta (2012), Belgium (2013), Denmark (2013) and Greece (2013). </P> <P> The European Hotelstars Union system is based on the earlier German hotelstars system that had widely influenced the hotel classifications in central Europe, with five stars and a Superior mark to flag extras . Instead of a strict minimum in room size and required shower facilities (e.g. a bath tub in a four - star hotel) there is a catalogue of criteria with 21 qualifications encompassing 270 elements, where some are mandatory for a star and others optional . The main criteria are in quality management, wellness and sleeping accommodation . In the catalogue of criteria each entry is associated with a number of points--each Hotelstars level requires a minimal sum of points besides some criteria being obligatory for the level . The minimum requirement for the Superior flag requires the same sum of points as for the next Hotelstars level which however was not awarded due to at least one obligatory requirement being left out . </P>
