The apartment is just a stone's throw from the Metro Trindade which runs straight from the airport.
This is a studio apartment so big enough for 2 people who are out and about all day. It is also equipped with everything you need
The location is right on a fairly busy fly-over, but that did not really bother us at night as we were out all day and slept like babies till the next morning. You do hear traffic noise, but not unusually high levels.
Everything is within walking distance to all the attractions in the center (for us 20 min walk is not a big deal) Otherwise use Uber or Bolt to get to places much quicker.
