I really liked spending time at Bruno's apartment. It's a very convenient spot between Copacabana and Ipanema. Walk a few minutes down the street, and you can feel the beaches of Rio! Moreover, it's a good location for any tours, which usually meet at the Copacabana Palace (about 15 minutes with taxi/Uber). Also, the underground station is just a few blocks away. If safety is your primary concern when travelling to Rio, Bruno's apartment is super safe with a friendly doorkeeper all the time. Across the street, you can find a good small supermarket. And in a walking distance, there are some excellent restaurants (I especially recommend Le pule with fantastic seafood and lamb).
And last but not least, Bruno is a friendly, kind and helpful person. He allowed me to leave my baggage in the room because my flight was in the afternoon. Thanks to that nice gesture, I could spend some more time walking and enjoying Rio without a feeling of a rush.
