Pedro’s apt is super clean and stylish, with extra touches like fruit, juice and water to welcome you. It has all that you need for a very comfortable stay (and two double beds in their own rooms) and is downtown. It’s great for walking to most areas. I would only say that the apt building is very old with an old fashioned lift so you know ahead of time, but the apt is very modern.
Though this top end of Santa Catarina looks a bit deserted, it is perfectly fine and as you walk a few blocks down, the street is all pedestrianised.
We had a great stay with my 12 year old child who also loved it (also close to metro stations but we used cheap and easy Uber quite a bit too.)
