1-Zimmer-Wohnung gesucht für 3 Monate! :)

Hi! I'm a 5th year medical student and I'm going to do an internship in Berlin this summer. I'm going to work at a GP in Berlin-Friedrichshain, so it would be very nice to find a 1-Zimmer-Wohnung in this cool neighbourhood! Ofcourse I'm aware that this is a popular neighbourhood, but I can always give it a shot.
I've lived in Amsterdam for 5-6 years now, alone and with roommates and I hope to find some nice people to share an apartment with in Berlin. I am open minded, I like to make music (I play piano and guitar, but unfortunately I can't bring them to Berlin), I can cook well (but don't want to brag too much) and I like to party every now and then. Besides going out, I also like to have a quiet evening and do things for myself. I'm open to try new sports and other things and I'm just very excited to explore this amazing city this summer! :)

And since I'm gonna work at a GP, I'm currently learning German so I'd love to practice!
