We were looking for a convenient apartment near public transportation for our 1st time in Berlin. We found so much more: the apartment is very convenient, with 3 areas for sleeping, relaxing and eating. It is located near a small transportation hub with busses, trams, S-bahn (train) and U-bhan (metro) all within 5mn. But more important it is in Pankov, a good neighbourhood of Berlin, with shops, bars, restaurants, convenience stores... so that it is also possible to experience the leaving like-a-Berliner experience.
And when our late arrival plane was also delayed, Barbara and her sister went out of their way with indications on how to get to the apartment and to meet us at the there, made our arrival a lot less stressful. So nice of them.
