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. Check-in is conducted remotely. To receive instructions, it is necessary to contact the accommodation one day before arrival, but no later than 10:00 PM on the day of arrival. Contact information is provided in the booking confirmation. Before check-in, each guest undergoes electronic verification by passport using the check-in service, and also signs an electronic contract. The guests will see the booking in the application and will have access to all the information about check-in on the day of arrival.
