21 year old woman looking for accommodation in Provedencia

I am a 20 year old (21 in July) woman looking for accommodation in Providencia or Downtown Santiago. I am a student from the United States and I study Graphic Design. I will be in Chile for 6 months to work. I am socialable but a calm and courteous roommate. I need a furnished room for 6 months. I prefer to live with people around my age (20-30) but I have no preference to whether this is students or young professionals, etc., I do not mind what gender my roommates are, and I do not mind pets. An apartment near the metro would be preferable.
