We liked the apartment and the neighborhood. There was great transit to the city and to the airport right outside the apartment. The apartment was clean and had everything we needed. The only thing that was a bit odd was on the second evening when we were accosted by the owner about shoes. I speak German and understood every word but did not have a clue what he was upset about. I had packed a second pair of shoes in my suitcase would I took out to wear the next door so I left the pair I had worn upon arrival down by the door as is typical in a German home. He met us at the top of the stairs to our apartment, coming out of a privat room that he had up there?? even though he and his wife lived downstairs. He started to berate us about the shoes and how they were not to be worn in the apartment. I explained that they had been packed and that I had taken them out and carried the downstairs to put them on. That did not satisfy him and he slammed back into his private room and closed the door. We did not have any more interactions with him after that. Other than that we enjoyed our time in Berlin and in the neighborhood.
