Sven and Henrik are wonderful hosts. They are clearly seasoned Airbnb professionals, in fact they have the whole process down to a science. The directions they provided were incredibly detailed, and perfect for those who have never been to Berlin. The apartment was very clean and well located (close to both the artsy part of town and the touristic sites), and an easy bus ride from TXL airport. Now about Sven and Henrik themselves - incredibly nice, wonderful hosts. Sven also gave us spot-on suggestions for touristy (and not so touristy) places to check out and, most importantly, the best place to try Berlin's famous currywurst! I would highly recommend their apartment for a great stay in Berlin.
