Daniels flat is superbly located for everything for short stays in Rio, the supermarket is around the corner (mundial), the Metro station is in good short walking distance with good late night food stands close to the station for cheap food and bars and restaurants for something more upmarket.
The bus stops are also in such close proximity to take you to many other convenient spots like Copocabana, the sugar loaf mountain and they run frequently, meaning if you really on a low budget you can also get buses home.
In the day time there's a local man selling fruit on a stand downstairs to the left of the apartment block, in front of Jeep which was also so convenient.
The wifi signal sometimes could be a bit weak, but not a major issue just slight inconvenience at times.
The flat is perfectly small for 2 persons, I travelled alone and felt it had just enough space, but if like me you only need a decent place to lay your head and freshen up, this spot will be highly suitable.
Rio is a brilliant place to travel but I highly recommend as a side note that if your portuguese is not strong, get a data package on your phone / a local SIM so you can utilise Google translate.
