Whichever you can, I think. Mainly there are three programs for studing abroad. The first one is Exchanging program.
If you choose this one, maybe you can choose whichever you want and you can even decide where to live by yourself like renting a room oro something like that.
In the other two programs, you may stay in the dormitory.
If you want more detailed information, you can ask to the SILS office.
