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. There is no reception desk; to check-in, you must notify the administration no later than 12:00 AM on the day of arrival and receive instructions for remote check-in. Contact details can be found on your booking confirmation.
