I stayed at Sabrina's place for Innotrans 2018. The Berlin Messe can be reached in 15 minutes with trains. U Bahn station was 3 minutes away and provided great connection to every where. Of course, Sabrina is a great host! Everything in the place was clean and well organized. I also enjoyed exchanging my thoughts and life experience with Sabrina. Thank you for the great time in Berlin. Would surely return the next time I'm in Berlin! :)
