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. Due to the dangerous epidemiological situation, the hotel only accepts guests on business trips. Upon arrival, guests must have with them a certificate of absence of coronavirus (must be issued no more than 2 days before arrival) and a document confirming the official purpose of the trip (trip order, official certificate, etc.).
