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. A deposit is required upon check-in to ensure property safety and adherence to house rules; it is refunded within 24 hours of departure. Check-in is contactless and requires an identification document of the person who booked the apartment. Strictly prohibited: smoking tobacco products in the apartment and common areas, staying with pets, disturbing the peace or hosting parties, guests under 18 without adult supervision, the presence of individuals not included in the booking, and the use of extra bedding by those not listed in the booking. Violation of these rules will result in the deposit being withheld or partially refunded in accordance with the extent of the damage incurred.
