Great location - a very short walk from the Hackesher Markt S-Bahn and tram station, two very close grocery stores. A few blocks to all the sights of the museum island area in one direction and to Alexanderplatz in the other direction.
Great apartment - large, clean and well equipped. An entertaining view of all the comings and goings of the train station area. Note that although the windows are well glazed, some train noise does come in. Earplugs are a standard and crucial part of our travel kit.
Great host - easy directions, timely communication.
