The thesis investigates the importance of interpersonal skills in the tourism rental industry. Interpersonal skills have become extremely desirable, but also unavoidable in businesses where the entrepreneur must establish communication and relationships, especially in service and tourism industries. For example, trends in tourism are becoming less based only on "sun and sea tourism", and more on the overall experience of the destination. Modern tourists increasingly appreciate the element of hospitality during their stay in the destination, and in that segment the key role is of the hosts of accommodation facilities and their individualized approach to guests. The interpersonal skills of the host thus represent one of the key elements for the satisfaction and attraction of tourists and ultimately of the business success of the accommodation facility. The empirical research aimed to determine the importance of the level of development of interpersonal skills of accommodation managers and to reveal the relationship between the level of development of these skills and business results. Based on the conducted empirical research, it is concluded that if the interpersonal skills of accommodation managers are more developed, it is more likely that the accommodation or host will be positively rated by the guest, in this case on the Booking.com website. Namely, Pearson's correlation coefficient between the degree of development of interpersonal skills of the accommodation manager and the rating for the hosts on the Booking.com portal was 0.623, which confirms the strong correlation between the observed variables.
