Exquisite!
We were traveling with another family, so there were six of us, two couples and two twelve year old's. We fit wonderfully. The two bathrooms and the three separate bedrooms made the difference. It sports a full living room, dining room and an eat in kitchen. The apartment is filled with light and air. Truly beautiful.
The location is also perfect. A short walk to two different major train stations, and bus stops.. walking distance to the Brandenburg Gate and the Reichstag. The neighborhood also has everything you might need.
I highly recommend this apartment especially for families or if you are traveling with friends.
