Together with my friends, we stayed at Prochor’s place. The apartment is very stylish, clean and well equipped and it’s 30 minutes away from the Schönefeld airport and 20 minutes from Alexanderplatz by train (S-ban). The stop is 15 minutes walking distance from the apartment. I didn’t get to meet Prochor personally, but my friends did and he was very welcoming and friendly and he even showed them how to start the fire in the fire place :). He was very responsive to our questions, send a very detailed description on how to reach his place and how to get in the apartment (map with explanation included) and left us tips on places to eat, shop and visit. All in all, perfect host and perfect place to stay while you’re visiting Berlin. Highly recommended!
