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. Early check-in and late check-out are subject to additional arrangements. An offer agreement must be signed upon check-in. A deposit is charged and returned within a day after check-out if the rules of residence are observed. It is prohibited to hold noisy events, drink alcohol, smoke cigarettes, electronic cigarettes, or hookahs in the apartments — the fine for violation is RUB 5,000.00. It is also prohibited to wear street shoes around the apartment. Silence must be observed from 10:00 PM to 9:00 AM and from 1:00 PM to 3:00 PM. Pets are not allowed. Check-in is only possible for guests over 22 years old, while persons under 18 years old can only stay with their parents. Corporate clients are provided with reporting documents.
