The topic of the final paper is the processing of the role and meaning of quality in the hospitality industry. Croatia is a tourist country, and a large part of its income comes from tourism, and for this reason it is necessary to offer high quality services in order to keep pace with the world offer and ensure further income from this activity. There are many definitions of quality but the comprehensive definition is to produce such a product or service that will meet customer requirements with its characteristics, which should tie it to the organization in the long run, which should ultimately bring profit to the company. So it is the customer who determines the quality. In order for a customer to realize the quality in a product or service, the company must take the necessary actions to ensure it. The increase in the importance of the quality of a product or service is the result of the growing and increasingly diverse needs of customers, which can be linked to the strengthening of globalization and competition and the development of new technologies. ISO 9000 standards, which have become recognized worldwide, provide guidance to companies on what quality means and how to achieve it. ISO standards can be applied in all industries, including hospitality and hotel. The standard has two properties: it defines, ie prescribes quality, but it is also a measure of achieving the prescribed quality. Another standard used in the hotel industry is the classification of hotels according to the number of stars. Although there is some general list of conditions that a hotel must meet in order to receive a particular star, every country in the world reserves the right to accept or set its own conditions. In Croatia, the Ordinance on the Classification, Categorization and Special Standards of Catering Facilities from the Group of Hotels prescribes the minimum catering services and conditions for the types and categories of catering facilities that make up the group of hotels. But regardless of the differences between countries, the guest can roughly know what to expect according to the number of stars of the object he chooses. The application of quality systems in hotels is given on the example of the Valamar Riviera Group.
