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. The front desk is open until 18:00. For check-in instructions, guests must contact the property before 06:00 PM. Contact information is provided in the booking confirmation. Upon check-in, a refundable security deposit equivalent to the cost of one night's stay is required.
