The city offers a wide variety of accommodation covering all kinds of travel budget and level of service. All types of accommodation in Ostrava, from luxury hotels to pensions, to youth hostels keep up with the tradition of Czech hospitality made up of attention, courtesy and care.

Like other cities in the Czech Republic, Ostrava uses the voluntary classification system for accommodation providers, according to the scope of their facilities and service.

Currently, there is no single world-wide classification system for accommodation providers. Regulations are often determined by individual governments, or professional associations and unions. There can be thus differences in the scope and quality of accommodation facilities boasting the same number of stars in your country and in the Czech Republic. However, the classes used for the accommodation providers in the Czech Republic are comparable with the European standards.
