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. Guests are required to contact the apartment in advance to receive check-in information. Check-in with the information already received is possible around the clock. Contact information is provided in the booking confirmation. If it is not possible to contact the apartment by phone number, the guest can send his question to WhatsApp.
