3 students looking for 2 rooms or apartment in Ljubljana

Hello! I am a geography student from Latvia and for next semester me and 2 geologists (a couple) are coming to Slovenia to study in University of Ljubljana. We are interested in renting an apartment or 2 rooms (one single and one double) in any part of Ljubljana.

The max price for rooms or apartment would be 500 eur "all included" (or by agreement). We are tidy, non-smoking in rooms or an apartment, really love to travel so there won`t be much time to make mess at home.

We are planning to stay in Ljubljana for 5 months - September (aprox. 27th) until the end of February.

Really hoping that some nice place is waiting for us.
Thanx.
Bye.
