Hi Everyone, my name is Otto and I live in lovely Kreuzberg, the center of Berlin. I love to meet new people. So I'd be happy to welcome you at my place and lern something new from you. By trade I'm a marketer. In my free-time I like to play sports, go out with my friends, and all the other random things Berlin has to offer. I also like to talk about science, universe and the meaning of life. I've lived all around the world and this city is the one I love, I'd be happy to share it with you.
