We spent an extended weekend at the great place on Werner-Voss Damm and found the place very homely and comfortable for a family of four (with teenagers). Fully equipped kitchen and brand new bathroom, nice high ceilings and comfortable sofa & and arm chair to rest after a long day exploring the city. Which is extremely easy to do from W-V Damm; Südkreuz train station is just down the street.
We are definitely coming back!
