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. Prepayment is charged on reservations with accommodation in apartments from April 26 to August 31 in the amount of one night. If canceled less than 30 days prior to arrival, the prepayment is not refundable.
