How to fund studies in Santiago? (Santiago de Chile)

Hola!
Next spring I will study for 6 months in Santiago de Chile (Universidad de Chile). As my university (University of Warsaw, Poland) doesn't provide students with any kind of scholarship for studies abroad in Chile, I'm currently looking for any possible grant, scholarship, fund, :) do you have any idea? Maybe some Foundation?
I'm trying to somehow calculate the costs so your help would be great in this subject too.
Also I'm thinking about accommodation, do you know some students' housing complexes/dormitories?
Greetings from Poland!
