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. Front desk is open 24/7. Guests are required to make a prepayment equal to the cost of one night's stay before arrival. A hotel representative will contact guests within a few days of booking to provide information on prepayment methods. Reservations without prepayment are held until 6:00 PM on the arrival date. After 6:00 PM, the reservation is cancelled.
