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. To book an apartment on the same day as the arrival, guests need to contact customer support in advance to confirm the possibility of same-day check-in. After making a reservation, guests should arrange with the apartment representative the time, place, and method for picking up the keys—this will help speed up the check-in process. Guests can find the representative’s contact details in the booking confirmation or request them from customer support.
