Sao Paulo will be a good place to stay, because here you have all the infrastructure, and easy to go to the other cities where there will be games (besides the games in SP). I live about 15 min by car from/to the Airport of Congonhas.
1 Room with bed, perfect for couple. Very nice, confortable, located in a Flat (hotel services included). Very good location, close to many restaurants, stores, 2 drug stores, 2 cinemas, 3 supermarkets, 1 gas (fuel) station, and 5 blocs walking to the Ibirapuera Park.
