Great experience. Feels like home, very awesome.
People: Antonio is the best host ever. He is very friendly and patient to give us advice about what to do the next day. His mom is very friendly too.
House: the apartment is beautiful. The room is quite spacious and beautiful too. Fits 3 people well.
Location: the best location in Rio. The neighborhood is safe and quiet. Very close to bus stations and the Botafogo subway that literarily take you everywhere in Rio you want, all within a reasonable amount of time (sometimes with transfers, but all pretty easy to manage, if you stay in other locations it might take you longer). The location is very close to Sugarloaf Mountain and Copacabana and Ipanema beach, also close to downtown and Lapa (close to everywhere).
Drawback: pretty much no disadvantages. The only thing is the room doesn't have big tables so you will have to put your stuffs on the ground/ chair/ on the small glass shelves.
You won't be disappointed with this choice, even will be surprised how fantastic it is!
