The place is exactly as it looks like in the photos. It's amazingly tasteful furnished and shows a lot of love for detail. It's located in a nice and quiet neighbourhood.
Lisa herself is a supernice host and left us some notes with recommendations on Cafés, Bars and Restaurants (thanks to which we could have Berlin's best burgers for dinner :)).
Compared to all the other places we stayed at, this is by far the best one, in all respects.
