Looking for a cheap double room

My name is Sofia, i'm from Granada, Spain, where im currently studying. I`m studying Psichology, and i would do my second year in Liubliana. Im very excited to begin my exchange semester there. I'm going with my boyfriend and it would perfect if we could find room to share together. I have Cat caller Gato ("Cat") and i would really love to take him with but i think i wouldn't be possible. If i find an apartment where are admited pets maybe i could take him with me..
