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 planning to check-in after check-in opening hours, they should contact the property in advance to get check-in instructions, the cost of nightly check-in is 100% higher than the price per night. Contact details can be found on the booking confirmation.
