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. Front desk is open 24/7. Check-in is carried out remotely, so guests must contact the apartment representative in advance by phone number for arrival instructions. Contact information can be found on the booking confirmation. Before check-in, the representative of the apartment contacts the guest via messenger and requests a photo of the passport, as well as a selfie with the passport.
