Anna's apartment is beautifully decorated and in a wonderful location. It's only a 5 minute walk from the nearest S-bahn station which will connect you to the rest of Berlin. Central Berlin (Alexanderplatz and Fredrictrase) is only a 30 minute train away and the local restaurants and large supermarket is only a 5 minute walk away. We stayed for a week and only interacted with Anna once but she was lovely.
