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. Know Before You Go • Parents or a legal guardian traveling with children under 18 years must present the child's birth certificate and an identity card with photo (passport, for example) at the check-in. For international travels from Brazil, if just one of the parents is traveling with the child, she/he must present – in addition to the child's certificate of birth and identity card with photo – a letter authorizing the trip signed by the other parent with a notarial certification of signature. In case the parents or the legal guardian, as applicable, cannot or are unwilling to give this authorization, a judicial authorization is required. People who intend to travel to Brazil with children must consult with the Brazilian consulate before traveling for more information. • Guests can arrange to bring pets by contacting the property directly, using the contact information on the booking confirmation.
