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 must be paid via bank transfer in 3 days after booking. The prepayment is non-refundable in cases of no-show or when guest cancels the booking.
