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. The day before the arrival, you must contact the apartment representatives to determine the time of arrival. Upon arrival, a security deposit of 2000 rubles is charged. The deposit is returned upon departure.
