We stayed here for a couple nights with 8 people. It was very nice! The street were the house is located is very calm and quiet. But if you walk 3 minutes down the road you are directly in the heart of Lapa with a lot of nightclubs, restaurants and bars.
The host was very friendly and communicative. Check in and check out went very smoothly.
I would definitely recommend this place and will return next time I am in Rio.
