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. After booking, before check-in, guests need to go through verification, namely: make a deposit, send a photo of the passport and a photo of the guest whose passport has been sent. Upon check-in, an agreement is concluded with the guest whose passport was sent before arrival. Around the clock check-in is possible if the booking is made before 10:00 PM. The reservation service is open until 10:00 PM. Guests are required to contact the property by 10:00 PM for check-in instructions. Contact details can be found on the booking confirmation.
