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 the cost of 1 night staying is required. The prepayment is not refundable when the booking is canceled less than 3 days before the arrival date. For bookings in the period from June 14 to July 5, the prepayment amount is 100% of the cost of living. Cancellation is not possible.
