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. The property has self check-in. For self check-in guests should contact the administrator in advance, before 10:00 PM, and receive check-in instructions.
