This is a superb apartment in a semi-residential area of Berlin, two or three stops on the U-Bahn from central Berlin. The building is altgebau (meaning it has heritage), with a marble staircase, and has been extensively renovated following German reunification. The apartment is spacious, with high ceilings and solid wooden floors. The decoration and outfitting has been done very well. (It gave me a few ideas for improving our own house). The apartment was also incredibly clean and tidy. The family has storage which they can move their effects into.
There are plenty of restaurants and cafés, and supermarkets in the area. Despite this the apartment, which is on the second floor, itself is very quiet. Having the bedrooms at the back means there's no street noise at night.
