The apartment is exactly as advertised and has all the necessary mod cons, including a fantastic wifi connection and cable TV. It's only 3mins walk to Copacabana beach and the front door is manned 24/7. There is ample sleeping space for 4 people and the kitchen facilities were decent. If you go to Rio by car, there are parking spaces right in front of the apartment, but you need sometimes to wait for a space.
The apartment is also close to bus stops if you need to use them to get around.
