I enjoyed my time in Berlin. The place is so local, you literally cross the street and you are at main station which will lead you everywhere. I did two bike tours which start at the TV Tower which was only 5 min walk away. One night I walked around the city and within the 2 hour walk managed to see most of the highlights. The views from room at lovely and when you open the windows you get a nice breeze. When taking the bus to airport it's once again walking distance and under 3 euros. The apartment has vintage interior which gives it charm and something different from modern apartments.
