24 year old girl, italian, looking for accomodation in Warsaw

Hi! I'm Isabella, I'm an Italian girl from Vicenza (near Venice) and I'm 24 years old. I'm a law student from the University of Trento and the next semester, from the end of September to the first days of February, I'm coming to Warsaw for an Erasmus experience...I can't wait! 

Now I'm attending the last year of university, I hope to graduate in March. 

I'm looking for a SINGLE ROOM in a flat to share with other university students (maximum 4), near the city centre and the university. My budget is around 250,00€ per month, other expenses can be excluded; in any case I can consider also room with a different budget. 

I've lived for 5 years in Trento with other students so I've learned to share my spaces and to live with other people. I'm a very organized person and respectful. I'd like to find sunny, nice and clean flat mates. 

Thank you!!!
