My boyfriend and I stayed in Lena's wonderful home for 4 nights. It is one of the cleanest, most stylish and fully equipped places I've stayed in with airbnb.
The interior is just lovely, very homely, with a large kitchen, bathroom (which was also extremely clean and functional) a living room and a cosy bedroom.
One of the best parts of our stay was the beautiful terrace, with two chairs and a small table, where you can enjoy the quiet view of the neightborhood.
The area is very quiet and 2 minutes from the metro (which is essential in Berlin to get around).
You would be lucky to spend your time in Lena's place, if you're in Berlin!
