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. When making a reservation, please indicate the estimated time of arrival for handing over the keys, but no later than 2 hours before arrival. After making a reservation, you must contact the object to clarify questions on the check-in.
