Barbara was very hepful when it came to providing a walk through of the apartment and all of the amenities. Her apartment and it's location was helpful in helping me understand Berlin and what it's like to live as a Berliner. Her apartment was beatifully decorated (on her own) which made my stay that much more pleasant. Public transit is advisable as walking may be out of the question for most destinations. FYI: don't forget the keys in the apartment as you'll have to pay a 30EU fee. I learned the hard way.
