We can highly recommend to stay in Aless' place! Everything is brand new (what a nice change to our first stay in Rio in one of those run down and pricy hotels), it's right in the middle of everything, very close to the beach of copacabana, walking distance to ipanema and also right next to a bus stop.
Also there are lots of dining options just around the corner as well as shopping both cloths or grocery.
On top of all these advantages, Aless was extremely helpful, replying all messages straight away and giving advices on transport etc.
Don't hesitate and book, you will not regret it :)
