23 year old looking for accommodation in Zagreb along with three other girls.

I am a 23-year-old law student who will study for a semester in Zagreb in the summer semester together with three other fellow law students. We are three calm and tidy girls. Several of us are also very fond of training and being active. We are looking for an apartment where there are 4 rooms, so that we each have our own room. We would prefer not to pay much more than 450 euros, but we are willing to pay more if the standars is good and the apartment is centrally located and close to the university.
