The flat is in the heart of Berlin, lots of interesting/ important/ useful places are nearby. It is big (3 bedrooms, plus a living room), but there is only one bathroom and no additional toilet. The kitchen is well-equipped. The internet connection was fast enough to check mails, read the news. Although the walls are thick, the flat is somehow noisy (when people moved around in the staircase it sounded that they were walking inside the flat). Overall, we were satisfied with this flat.
