I stayed in Grit's flat for a month while I was in Berlin for work. It was the perfect home away from home. Spacious, clean, comfortable and very conveniently located, I would definitely recommend the flat for long-term stay. Grit was very helpful and accommodating for my check-in and check-out times and was always quick to reply to any questions I had. She even let me use her bicycle during my stay which is the best way to get around Berlin. I'd definitely stay again next time I'm in Berlin and recommend Grit's flat to anyone. Thanks Grit!
