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. Airport or train station transfers can be arranged upon request for an additional fee. Contact information is provided in the booking confirmation. For longer stays, cleaning is available upon request and will be discussed individually. Check-in and check-out times are agreed upon individually.
