We are currently in Paris and have already been expatriated to Spain; we will be in Brazil in January and I am looking for information on how to settle as an expatriate either in Sao Paulo or rather in Rio (I can choose) What is the cost of housing for a nice apartment or house for a family with 2 children (4 and 9 years old)? What is the income tax? What are the pleasant and safe neighborhoods in these two cities? Any useful information to know Thank you all in advance Eric
