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. Check-in takes place contactless, after the guest is verified through the remote check-in service. In the same application, the contract is signed and the remaining payment is deposited, if necessary. The facility is not suitable for events and parties. It is forbidden to smoke any kind of smoking mixtures, light incense and any pyrotechnics in the facility — sparklers, candles, etc. Final cleaning and a deposit are paid additionally and are a prerequisite for the stay.
