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. Check-in is possible until 20:00. Late check-in is possible only by prior agreement. To arrange a late check-in, guests must contact the property in advance at the number indicated on the booking confirmation.
