we spent a wonderfull reveillon in Silvia's apartment.
first of all, the apartment is very pleasent and convenient, very central and well located if you want to see most parts of the city (and not only the beaches), with a supermarket nearby and the metro, taxi just down the street.
The flat is cool, well equipped and practical (wifi, washing machine, microwave, fans... (but no air conditioning, be aware of that, it can be very hot in summer)) and it's just like on the photos, bright and clean.
we enjoyed the hammock watching TV in the morning, it was easy for us to feel like home
at last but not least, Silvia is a great host, It was my first time on airbnb and she made it very easy, she always answers quickly. She gave us tips and good addresses in Rio, we knew we could count on her in case of problem (but everything was OK)
