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 to the apartment is contactless or no-contact. Guests are required to contact the apartment in advance to receive check-in information. Check-in with the information received is possible until 23:00. Contact information is provided in the booking confirmation. If it is not possible to contact the apartment by phone number, the guest can send their question to WhatsApp or email.
