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 is available 24/7, either through a smart lock or in person. A security deposit and a photo of the first page of your passport are required upon check-in. Noisy events, smoking, drinking alcohol, and pets are prohibited in the apartment. The deposit is non-refundable if the rules are violated.
