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. There are no double beds in the Standard Room or the Comfort Room - there are only two twin beds that can be moved together. Also, the Standard and Comfort rooms have a 3-star level. Upon check-in, a certificate of the epidemiological environment is required, which is valid for 3 days before arrival. A certificate must necessarily be marked with a note that the person has not been in contact with a sick COVID-19 for 14 days.
