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. Check-in is carried out remotely. For instructions, guests should contact the property the day before arrival, but no later than 02: 00. Contact details can be found on the booking confirmation. The refundable deposit is paid upon check-in in cash or by bank transfer.
