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. Self-check-in, check-in information is provided after providing a passport and transferring the deposit and the remaining amount wirelessly to the account. Early check-in or late check-out is possible, but cannot be guaranteed. A full package of accounting documents is provided for business travelers. The deposit is refunded after cleaning, before 22:00 on the day of departure. If violations are detected — smoking, guests over those specified in the booking, parties, neighbors complaining about noise — the deposit will not be refunded. Damage, loss of items — fine is paid based on the current market value.
