Looking for a place in Brussels

Hi, 

I´m going to be doing an internship in the EP and need to move to Brussels for that. I´m an open and outward going person and generally, good company to have in the house. 
I´m looking for a place for 3 months with the possibility of extending that. 

I´m not fussy about the type of accommodation. I would appreciate roommates who take responsibility for their space and socialize on occasion.
