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. The accommodation does not provide information on bookings. All booking information is indicated in the vouchers. Upon check-in, the guest must give his last name and inform the staff of the accommodation facility that the check-in voucher is at the post office of the accommodation facility.
