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. To check-in, guests must contact the check-in manager at the contact number one day in advance and receive check-in instructions. Calls and messages are accepted from 7:00 АМ to 11:00 РМ. You can also provide information through messengers.
