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 passport is required upon check-in. Guests must be 18 years of age or older to check in. The apartment is not suitable for special events. Smoking is prohibited in the apartment or on the balcony. If the smell of tobacco is detected, the deposit will not be refunded. The deposit will be returned upon check-out after cleaning. Intoxicated guests will be denied check-in. Registered documents — a contract and a receipt from the Samozanyatyi app — are required.
