I agree with the comments below. We had a nice stay at Marcelo's appartment. It is very well located, easy to access and communication (or lack of) was very good with the host and the doormen of the building.

However, it is true the flat can get very dark (only one window in the bedroom) and very hot (the air con doesn't reach the main room). The air con is also very noisy when it is on - which makes it hard to sleep at night.

All in all, a good experience for a couple of days in Rio.
