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. To confirm the reservation will be charged. The guest should also contact the representative of the apartment at least 3 days before the date of arrival and pay an insurance deposit of RUB 2,000.00. All payments are accepted only by credit card. The deposit is returned on the day of departure by transfer to the card (perhaps a few hours after the check-out).
