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 second flat with similar renovations is located next door. Both flats can be booked simultaneously to accommodate a group of 2 to 4 people. Children without a separate bed are accommodated at no extra charge.
