I'm a prospective international student looking for accommodation for the winter semester, in Lüneburg

I'm a very joyful person who likes talking and being around people, I enjoy music and I'm an extrovert. I'd want to be around similar people who are open to new ideas and who are adventurous and outgoing. I'll be studying at the University of lüneburg, if I could get similar schoolmates as well it would be great, as well as people who are familiar with the city, or even international students as well, we'll figure out things together. I don't smoke, nor drink, so I'd like to be at a place where there is no smoking and the people are sober. I don't mind pets.
