Stayed here for 5 nights during New Year and it was a perfect location only two blocks from the Copacabana. Adilson and his wife met us when we arrived, even though we arrived late and were very helpful. Adilson himself didn't speak English, but his wife does, and they even brought a English-speaking friend so the communication was smooth.
The apartment is not big, but it's big enough for 5 if you keep it organized.
There's no WiFi here, but it's available in restaurants nearby.
