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. Each guest is required to provide a photo of their passport at check-in. Check-in is contactless; guests must contact the property in advance using the phone number provided in the booking confirmation. There may be disruptions with mobile internet in the region, so guests are advised to contact the property beforehand.
