We loved our stay at Karsten's place. He was welcoming even when we got in a bit late in the evening. His roommates were also nice and everyone was quiet and respectful about shared spaces- especially the bathroom in the mornings:). The room itself is so beautiful we wish it was ours at home. It is large, and the bed is so comfortable we ended up sleeping in one day when we didn't even want to! The neighborhood is perfect to wander for dinner (and ice cream!!) / shopping and the tram and Metro are very close nearby to get even more into the center of Berlin. You can also walk many places as well. We couldn't think of a better area to crash at night after a day of exploring. We had a great stay- many thanks, Karsten!
