The apartment is located super close to the S-Bahn station and walking distance to tram stations, which makes it perfect to reach other parts of the city.
It was a comfortable weekend in Berlin, as the place is cozy and had all the amenities for having a good breakfast and dinner at home (if one chooses -- there are two good markets around the corner). Alternatively, good restaurants and bars are easily reached by tram.
We had a minor hiccup with the internet in the morning, but Natalie was a great host and managed to get it fixed quickly.
