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 double occupancy, if guests require separate beds, a fee of 500.00 RUB is charged for additional bed linen. An extra bed is only provided upon notification at least 24 hours prior to arrival and payment. Requests on the day of check-in are not guaranteed. For reservations for 3-4 guests, a sofa and bed are provided (bed linen and two double blankets are included). Extra blankets are not provided.
