21 year old girl looking for accommodation in Mainz

I´m 21 year old, and I´m going to Mainz for one semestar in January. 
I see myself as a person who loves meeting new people and cultures. I´m confident and very positive person. I´m looking for someone who will be kind to help me first few days, and maybe later we could hang out, also the important thing about accomodation is to have a kitchen, because I like to cook and eat healthy food. :)
