I really liked staying at Malte´s cool, light and stylish flat although it is situated in an area dominated by Lebanese people but of course, this is part of Berlin, too. Anyway it is a good starting point to explore Berlin as the underground as well as busses are just around the corner.
But before leaving Neukölln you have to go to one of the most chilling spots there, the Klunkerkranich’s nest site at the roof of Neuköllln Arcaden in Karl-Marx-Strasse 66: http://www.klunkerkranich.de

All in all: Everything was fine, clean and I felt comfortable at Malte´s flat. Above all Malte was all that friendly and very communicative. Thumbs up!
