Karsten was such a great host! He greeted us at his apartment and took the time to sit down and show us the best things to do in Berlin. He even compiled a list of restaurants and fun places to go to in the city and emailed it to us after our meeting. The apartment is really close to the train station and we were able to easily commute to wherever we needed to go. The apartment was so nicely designed and very comfortable. We really felt at home during our stay in Berlin. We highly recommend Karsten's apartment. Thank you for being so awesome Karsten! :)
