20 year old intern in Architecture looking for a room (possibly with 1 or 2 flatmates)

HI, I am an Italian student in the UK. I am going to be working as an intern in Rotterdam for the next 5 months. I am looking for a room to rent, in a clean and cozy appartment with 1 or 2 flatmates. I am looking for a room with a sunny atmosphere, a double bed and an ensuite bathroom would be ideal but not necessary. I am very sociable and like meeting new people. I will be working full time so I won't stay in the house all the time.
