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. Guests must have their passport with them upon check-in. A deposit is required for accommodations and is refundable upon check-out if the accommodation conditions are met (within 2-3 hours). Payment can be made by card (online transfer) or in cash. Accommodation is only suitable for families with children ages 6 and older. Smoking is strictly prohibited in the flat, as are events and parties. Pets are not allowed. The flat is under video surveillance. No noise is required from 10:00 PM to 8:00 AM.
