Best place to study in Shanghai?

[mr tin]

Hi, i'm brazillian, and i plan to go to Shanghai in 2009 to study the language.I'm already having classes in Brazil (beginner level), but i want to have a more intensive experience.What are the best schools in Shanghai (considering i have only six months to stay, due to my work)?I've checked out GEOS (www.geosshanghai.com), Mandarin House (www.mandarinhouse.cn) and a few others, but i think it's good to hear from people that actually know which ones are really good places.Thanks in advance (and sorry for the poor english).Cheers!Alfredo Cardoso alfredocardoso@gmail.com
