Arnd's place is cozy, nice and sunny and very centrally located. Ideal for a stay of a couple of days to explore this lovely city. Arnd was the perfect host, communicating clearly and immediately, and very accommodating when we had to freshen up late in the evening before heading out. Do spend some time in their lovely living room looking at his extensive train models and have breakfast on their lovely little balcony. We would love to come back when we return to Berlin!
