Duda’s place is as described.
Thought the building may look old (they all are in that part of Rio), the apartment is renovated, modern and functional.
Location cannot be beaten and amenities around the apartment are plentiful. Several markets/ supermarkets, pharmacies and restaurantes are a very short walk from the apartment. Copacabana beach is one block away.
Communication was easy and fast with the host and, while I have never met Duda, key was available with the doorman.
If there is one thing to complain is that the street where the apartment is located is very busy and, while the apartment is on a high floor, one can hear all the traffic noise. So for the light sleepers, bring a earplug.
