I absolutely loved my stay at Bernd and Katja's. It was my first trip to Berlin and they were very helpful with suggestions on everything! Their friend Marcel met me at the apartment for check in, he was lovely and the apartment was absolutely immaculate. Loved having coffee on the balcony in the morning (even though it was chilly!), and coming home at night to such a calm, inviting space. Would definitely stay again the next time I am in Berlin!
