20 year old girl looking for accommodation in Milan for 3 months.

Hi! My name is Mariana. I'm Latin American, I speak fluent English and Spanish. I will be taking a 3 month class to learn Italian, so I am looking for a place to stay, preferrably with female roomates. I would like a private room and if possible for the final price to cover utilities and expenses. Also, for it to have a good location with easy access to metro stations. I'm easy going, do not disturb, and like to keep my place clean. 
I look forward to meeting people and experiencing life in Milan!
