Apartment needed near Prenzlauerberg

Looking for 1 or 2 room apartment somewhere close to Prenzlauer berg. I would prefer a furnished apartment, also open to consider shared apartments. I am looking for a place as soon as possible, and would prefer at least 1 month stay. I am starting to work at an office near Kollwitzplatz, and would prefer an easy commute to work.

I am an engineer from Finland, and will be working with an start-up. I have no pets and don't smoke. I will be living alone. I live quietly and respectfully towards neighbors, in Berlin I will be working most of the time, so I will mainly just need a place to sleep.

I speak also German, as I have lived in Switzerland as a high school student, but not so sure about my skills so writing this in English :) I like traveling and doing things outdoors such as skiing, snowboarding, kite-surfing and hiking.
