Nowadays, it is increasingly popular accommodation reservation using various online agencies. In this way, tourists receive all necessary information about accommodation - location where accommodation capacity is available, information about the accommodation unit itself (accommodation, equipment, size, additional facilities) and availability in selected terms and prices according to terms and number of persons. Online reviews can be defined as transferring experiences among potential and existing service users. They can be defined in more detail as a form of virtual oral submission between users who share information about the positive and / or negative characteristics of products and services, movies, books and the like, and are available through the Internet. Reviews are one-way recommendations that consumers express their pay-per-pleasure. Also, consumer reviews are used as a source of information when evaluating alternatives in the buying decision process. On the other hand, reviews to bidders provide insight into customer satisfaction, or dissatisfaction. Guests at Booking.com, TripAdvisor and Airbnb have the ability to leave their impressions and comments on portals. Through these portal guests have the opportunity to express their opinions and level of satisfaction with the basic and additional services, accommodation and the host itself. The aim of the research was to determine the attitude of the respondents and their habits when choosing the accommodation. The study was conducted in the period from April 10 to April 24, 2019, on a sample of 51 respondents. Research has shown that online reviews may affect a hotel's reservation decision and bad online reviews may encourage guests to give up reservations.
