The concept for our own hotel brands Sentido, Calimera, Primasol, Ananea and Playitas is based on recommendations from the World Health Organisation (WHO) and well-known hygiene companies with whom DERTOUR Group already works in the destinations. In addition, DERTOUR Group draws on the expertise and advice of the well-known analytical laboratory of Dr. Andreas Kneißler. In this way, we prepare our hotels for the implementation of national hygiene standards adapted to the Corona crisis. For the further development of the document and the relaunch of our travel business, DERTOUR Group is in continuous close exchange with the national and international authorities.
