I had a very special stay with Arne (& the cats). The apartment was simply beautiful. The concrete walls have been maintained, suggesting the older Eastern character of the building, made complete with Arne's personal touches and furnishings. There was a sense of lifestyle and life about Arne's place that I haven't had at other Airbnb's. It really was the perfect Berlin stay.
Being in Mitte, everything is within walking distance of trains as much as it can be in Berlin. For reference, it was about 10 minutes AlexanderPlatz. Mitte felt Boutique-ee and would suit anyone into that.
Arne kept a perfectly clean home too.
Book it.
