Frank's place is super cool and we enjoyed being his guests. It's a real artist's house and the decorations are very special. Be sure to look at the super-expensive floor. Located near to a metro station, it is convenient to go anywhere. Frank is a nice host. Although we didn't meet too much during our stay, he prepared everything carefully for us. We had a perfect weekend in Berlin. And for any of you who wanna go to Berlin, I would like to recommend Frank's place as a perfect choice.
