The stars-classification of DEHOGA (German Hotels and Restaurants Association)
 Although the DEHOGA classification should be the official one, only about 50% of the hotels accept this and the classification criteria.
In several cases the rating in stars is higher than the rating used by international recognised hotelguides.
