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. If guests check in between 25.09.2025 and 15.10.2025, they should contact the property exclusively via messenger, as phone calls are not available during this period. Contact details can be found on the booking confirmation.
