Staying at Marine's place was an absolute pleasure. My friend and I stayed for 2 months in the spacious and functional apartment. It has everything you need to stay comfortably for a long or short time. By the end it started to feel like a home for us.
It is in the beautiful area of Prenzlauer Berg and very close to a tram and S-bahn station.
Marine was very kind and helpful during the stay and I can definitely recommend staying in her apartment.
