21 year old girl, looking for accomodation near Unidersidad de Juan Carlos Rey

I'm looking for a studio, or an apartment shared only by girls. I am an easy-going person, I do chores and I always keep my space clean. No worries about this, but maybe sometimes I''ll want to accomodate my bf for a few days(4). I speak spanish, english and greek and I'm really quite as a person, and I want my roommates to make no noise too, I have no problem with other guests. Also I always smile and I want my roommates to be pleasant. The apartment it would be perfect if it has maximum 4 rooms but no problem with more. But the best is one bathroom to be used by 2-3 people max. I need a furnished apartment, I don't care about the decor, but I prefer a double bed( single beds not declined). Finally I don't have problem if the bills aren't included.
