18 Year old female attending Leiden University looking for a female student roommate

I am and 18 year old female Swedish citizen moving from Marbella, Spain to attend Leiden University in The Hague.  My major is International Relations and English is primary language, but I also speak Spanish and Farsi.  I prefer a female roommate who is also a student.  I am very chill and laid back so I would like someone similar. I have no preference in age or nationality as long as as they are independent.  I prefer someone who is clean and helpful around the house.  I am new to the country so I would love to make new friends.

As far as accomodations, I would like to live close to the city center in a safe neighborhood considering I am a young female by myself.  Also, I prefer to have my own room  but I do not mind sharing the bathroom, living room and kitchen.  

Also, I need a furnished apartment.
