The requirements for documents needed at check-in depend on the type of accommodation and the applicable regulations. For hotels and other accommodation facilities, a Russian passport, an international passport, or a driver’s license may be accepted. For apartments, serviced apartments, and other properties where check-in or contract conclusion is carried out according to the rules of a specific property, the required documents are determined by the property itself. Before check-in, guests must contact the check-in manager in advance, no later than one day before check-in. In case of planned check-in after 20:00, it is also necessary to notify the manager in advance. Contact information is provided in the booking confirmation.
