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. With a paid reservation, check-in is from 14:00 to 23:00. In case of unpaid reservation — from 14:00 to 18:00. If guests plan to check in later than this time, they should contact a representative of the apartment. Contact details can be found on the booking confirmation. Immediately after booking, guests should contact the property to arrange the time of check-in. If check-in is on the day of the booking, then check-in takes place in available time windows. Contact information is provided on the booking confirmation. The second and subsequent sets of bed linen are provided at an additional cost.
