Italian girl Erasmus trainee looking for a room from January

Hi! I’m an Italian girl looking for a single room in the city centre of Zagreb from January until April 2016. I need an apartment with internet wi-fi and washing machine, possibly with no smoking people. I can share the flat with other workers (I’m an Erasmus trainee), even a flat for only 2 or 3 people is ok. I’m a quiet and tidy girl, I’ve already lived with other flatmates in Venice. I’ll work in Sesveta, but I consider other areas in the centre. Around 150-200 euro per month. Thank you!
