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 front desk is open until 21:00. Late check-in after 09:00 PM is possible only by prior arrangement; it is necessary to contact the provided phone number, otherwise check-in will not be possible. There is no contactless check-in in the flat.
