The host was welcoming and was courteous enough for the key handover late in the evening. The apartment is centrally located and was very nice with all the necessities. A lot of Berlin landmarks are a stop or two away via metro trains or trams.
I am satisfied with my stay at the apartment.

Though, If someone would have put a gun to my head and have asked me to find something I didn't like about the my stay, it would be this...I visited Berlin in the second week of August and the temperature was in high 30s. Since the apartment is located on the inside of the building cluster with only windows and no balcony or fans, it was very hot and difficult to sleep with only windows open. But the rain Gods came to our rescue on the last couple of days. I am sure this would not be a problem at other times of the year.
With all said and done, I would certainly like to stay at Stamatis' apartment.
