Gerhard came and guided us from the Suedkruez train station to the apartment. At first we had a problem with the wifi, so Gerhard got a new unit for us. He gave us plenty of tips about where to shop and eat in the neighborhood, and we took full advantage of his advice. The neighborhood is known as the Island, because it is within a triangle formed the 3 S-Bahn lines. There are plenty of interesting areas to walk to, and getting to other sights in the city is very easy with the S and U bahns. Jeanne and I heartily recommend Gerhard's apartment to other Berlin visitors.
