Karsten’s place is cute and perfect for exploring Berlin. It has nice high ceilings and big windows that give the place an airy feel with lots of light. We opened the windows for a nice breeze. It’s on the ground floor so you get some folks walking by but that didn’t bother us much. The bathroom area has a door and the bed area has some walls around it so you have adequate privacy. The kitchen is small and no microwave but Karsten has lots of useful supplies stocked - we enjoyed the coffee! Walking distance from the metro and there is a WONDERFUL little restaurant just around the corner with their own brewed beer and German food we loved. Grocery store and Berlin Wall memorial are a short walk away. Plenty of hot water for shower. We would stay here again and highly recommend it!
