Excellent location and a perfect apartment! We would absolutely stay here again. There was three of us and even the spare bed was just as comfortable as the real bed. Alan met us and went out of his way to bring outlet converters and point us in the right direction as to the best places to go in Berlin. And Kasia was always so quick to respond by email to any questions we had. Both of them helped make our stay better and if we return to Berlin we will definitely be checking their availability! :)
