It's an apartment located in a fairly quiet area of Berlin, with easy access to the S-Bahn and within walking distance of a grocery store. The bed is a foldout, but not uncomfortable, the kitchen is efficiently sized and has an oven, and the space has a lot of natural light. Don't pack a lot, because the apartment is a bit of a tight squeeze and there just isn't much room if you travel with more than a backpack and carry-on suitcase.
