I am in East Berlin, so I certainly disagree. And most places in the East that are single family housing are nice anyways. For example, the borough Hellersdorf-Marzahn contains the big 12-level blocks of Hellersdorf, Marzahn and Kaulsdorf-Nord with problems up and down, but also ~30k single family houses in Biesdorf, Kaulsdorf and Mahlsdorf (as well as the original village of Marzahn, not much left of Hellersdorf) that are super safe and more and more expensive. Localities that are not so nice (but again, it depends on the exact location) are Tiergarten, Wedding, Hohenschönhausen, Weissensee, Hellersdorf, Marzahn, Neukölln (the locality). Basically, cheap places are cheap for a reason.
