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 working hours of the reservation department and receiving incoming calls are from 05:00 AM to 10:00 PM Moscow time. Check-in is contactless, through keyboxes and electronic locks. Therefore, before check-in, guests sign the offer agreement electronically and pay a deposit. Links are sent in advance — 24 hours before arrival. If the guest does not get in touch and does not check in, after 10:00 PM Moscow time, he/she will not be able to check in.
