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. A prepayment of RUB 2500.00 should be paid via bank transfer. Before check-in, the guest must send a selfie with a passport to confirm their identity, as check-in takes place remotely.
