International Airport direct taxi journey takes 30 minutes and costs R$ 50 / 60. Or you can take the special bus of Real Auto Bus (Premium 2101 or 2145) for R$13 to Santos Dumont Airport and a R$12 taxi ride to BananaZ. The total cost is R$25. You can also come walking and enjoying the beauty of the city. It takes about 20 minutes.
From Rodoviaria Novo Rio, best is a taxi for R$12. If not, many buses (like line 386) will drop you very close. Just ask the driver for Arcos da Lapa, we are 300 meters away from that reference point.
