Claudia's place was very clean and very quiet; even though the street was busy and noisy at night, by the time you get in to Claudia's place, you can't hear any street or other noise. The place is very close to nice cafes and to the U-Bahn. Only 10 mins walk to Potsdamer Platz, where there are lots of bars, cafes restaurants and a big supermarket. Nice walk to the park and less than 30 mins walk to the Brandenburg Gate and Bundestag. Highly recommended.
