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. Birth certificates must be presented for all children under the age of 14. If the child is traveling with a relative, except for parents, or a guardian, documents confirming his right to accompany the child must also be presented upon arrival. One child under 6 years of age stays at the hotel free of charge, provided that a parent/guardian is accommodated in the room without providing an extra bed. Foreign nationals: Adults and children must present a valid passport, visa and migration card upon arrival.
