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 20% of the booking cost must be paid in 5 days after booking. Free cancelation of the booking is possible no later than 14 days before arrival. Otherwise, a fine of the cost of 1 night staying is required.
