where to go in Brazil for a week?
 

I am heading down to Sao Paulo for biz come February.
While down there I want to get the fuck out of the big crazy cities and take a week to do nothing. Just enjoy summer and sit on the beaches.

any suggestions, I am considering:

Fernando de Noronha, Natal, Buzios, Fortaleza or even heading down south to Floripa.

any suggestions or natives who live down there pls give me suggestions.

thx
