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. After booking guest must contact the apartment to clarify the details. A prepayment of 100% will be charged. If guest cancels the reservation and no-show, he will be charged a penalty of 1 night's accommodation. For bookings for the period from June 15 to July 9, 2018, prepayment is not refundable in case of cancellation.
