2 romms in shared flat needed (Buenos Aires)

Hey everybody
my name is Nico and I´m a student from Germany.I´m 24 years old and me and a friend of mine are looking for 2 rooms in a shared flat with other spanisch speaking people.
We are both studying Tourism for one semester at the U.B.A. and are "buena gente" : )
If you know any place with one or two rooms available please let me know...
Cheers
Nico
