New in Milan!!!

Hi everyone!!!
My name is Juliana, a brazilian from São Paulo and I just moved to Milan four days ago!!!!
I am here for a Master in International Relations at Cattolica and I still need to adjust myself to the new town.... :)
Would really love to meet new people and make some friends!!!!
Also, if anyone has any info on people wanting some Portuguese or English classes... and I would really appreciate if anyone knows of a room available to rent?!! My classes are close to Sant'Ambrogio metro station so a place in this area, Duomo, Porta Genova or Navigli would be the ideal!!
I sure hope we can meet soon in some get together.... thank you all!!!
Ciao!!! Juliana
