Erasmus film student looking for accomodation in Brussels.

Hi! I'm Anastasia, I'm 23 years old and I'm coming to Brussels with an Erasmus scholarship to study cinema at ULB. I'm interested in renting a place (room, studio, shared flat, collocation, etc.) at 450 EUR maximum price, charges included. I'm friendly and tidy, will spend most of the time in the University library or discovering the city most probably, so I just want a cozy place that feels like home. I'd like my boyfriend to come and visit and spend one month with me at the beginning of my stay Brussels so a double bed would be perfect.
