Just wow ! Christoph's appartement is one of my favourite airbnb places I've been to.
It's not your run of the mill airbnb filled with basic Ikea furniture. The place is huge, tastefully decorated and full of artwork. You have a panoramic view of the whole area, and the terrace faces sunset, perfect for relaxing with a glass of wine after a day exploring the city. It is located in the heart of west Berlin, the area is packed with shops and restaurants, and the subway station (U Bahn) is very close (less than 5 mins on foot), but then I'd personnaly recommend that you use a bike, Berlin is a wonderful city to explore on a bicycle !
Christoph himself is a really nice guy, and he gave me excellent advices about the city, fantastic restaurants, things to do and places to visit. Highly recommended ! Thanks again for having me !
