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 available upon agreement. Pets are allowed upon request for animals weighing up to 10 kg; large dogs and multiple pets are not permitted. The deposit is refunded on the day of check-out after inspection of the flat.
