Lisa's apartment is wonderfully peaceful yet very central with easy access to the underground. As many have said, there are lots of stairs but it means the flat is nice and airy. It was immaculately clean with well stocked kitchen including a Nespresso machine and large TV. The outside of the flat (in true Berlin style) is covered in graffiti but don't let this put you off - it adds to the character. There are lots of cafés and restaurants in easy walking distance and it makes a great base for exploring Berlin. Finally, Lisa herself is really friendly and helpful and was very communicative in arranging the booking. Would definitely recommend this flat.
