Young professional looking for studio or 2 zimmer apartment!

I am 24 years old, half Swedish half Costa Rican! I will be working at the International Council on Clean Transportation in Berlin. I am really passionate about sustainability efforts, climate change awareness and public health, and so decided to devote my career to finding solutions to such issues.

In my leisure time, I love to run outdoors, try new restaurants, read books about science and personal growth development in order to try to become a better human and scientist. As a full time employee and fellow at the ICCT I will be earning a stable monthly income, additionally I will also be working as a part time consultant at ISGlobal (Instituto de Salud Global Barcelona), where I will also receive an extra monthly income.

I am looking for a studio apartment or a 1.5/2 zimmer apartment starting mid January, for long term. Or a room in a shared WG apartment. Preferably in the areas of Prenzlauer Berg, Kreuzberg, Mitte, or Moabit. I am very clean and responsible, have no pets, non-smoker, very eco-friendly.
