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. For a one-night stay, the cleaning fee is RUB 4000.00. For two nights or more, cleaning is included in the price. Check-in is by arrangement — it is necessary to contact in advance and provide the expected check-in time, preferably 4 hours prior. Requests are accepted during working hours from 08:00 AM to 11:00 PM. Contact information is provided in the booking confirmation.
