Lithuania is a member of the European Hotelstars Union, which provides a harmonised hotel classification with common criteria and procedures in the participating countries. Vilnius has six 5-star hotels, all located in the Vilnius Old Town. There are also 27 4-star hotels. The Grand Hotel Kempinski Vilnius, with a direct view of the Cathedral Square, is considered as the most luxurious hotel in Vilnius and offers presidential rooms for around €3,000 per night (more than three times the average monthly net salary in Vilnius) and is frequently chosen by the heads of state, movie stars, famous musicians and other celebrities during their visits to Lithuania.
