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. When booking, please provide a guest contact number. Check-in to the apartment is done remotely using a coded lock. For further instructions, guests are required to contact the apartment 24 hours prior to arrival using the number provided in the booking confirmation.
