A masters student lookin for accomodation in berlin

i am a quiet person who always want to be around positive mined people. i need a quiet environment and flatmates. i respect everybody i come across.  I am a christian and would be a delight to me if i meet people alike.  I want a shared apartment where i can have an overnight guest since my boyfriend may come around sometimes.  doing cleaning is not a problem to me at all.  in as much as i like cleaning means that i want to be with people who like clean and tidy environments, flatmates who like tidying up the flat always.  if i get a jobs around where the flat is located, thats fine if not, it also ok since my main priority is to study.  i like reading, listening to good music and sometimes watching movies.  i neither smoke nor drink so if i get flatmates like that, i will be very glad.
