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 guest passes electronic passport verification using the check-in service, where an electronic contract is signed. Final cleaning is paid extra. For stays of more than 1 week, a mandatory cleaning service and linen change are provided for an additional fee of RUB 1000.00. Early check-in and late check-out are available upon request. Round-the-clock check-in is possible if you make a reservation with full payment before 11:00 PM.
