The description of the place in the add is correct: it is a lovely place equipped with all one needs to enjoy comfortable days in Rio.
Pros: location, distribution of the space in the apartment, furniture and equipment in general.

Cons: It is a little noisy on Thursdays and Sundays. Gavea is a meeting point for young locals and they hang out very close to the apartment on Th & Sun. I must say that this "background noise" is not intrusive and I actually like it; it provided enough noise for me to read (without dozing off), but not too much so I can't sleep. Also, observe that this is not a "con" of the apartment itself.

I would highly recommend this place.
