Two 20 years old girls , looking for accommodation in Rotterdam

My name is Sona I am coming to Rotterdam with my friend Adriana to study at Rotterdam business school. We are from Slovakia where we lived in a beautiful small city Zilina. Although we decided to change our lives and start new ones in a bigger city.  We are looking for a furnished place to stay in the centre of the Rotterdam. Which can be a room in a flatshare, private room or an apartmant. We are easy-going, polite, responsible girls who like to meet new people. We are always ready for an advanture but we can also enjoy a quiet night at home.
