The apartment is nice, spacious and in quiet neighbourhood. Though you should know that to exchange money you will need to go to Copacabana as for some reasons they don't exchange money everywhere in Rio.
It's really amazing to go to a balcony in the morning just to enjoy a quiet street.
The taxi to main sights is not that expensive as we could expact, so as we were three it was around same price as for the bus.
The apartment really lacks a washing machine especially if you are a longstayer. And mind that sorted recyclable garbage is being taken away only once a week, so if you don't plan to throw everything together as nonrecyclable, you will need to keep it in.
Generally I would recommend the apartment and would come back to it again.
