The owners of this apartment are very pleasant folks, fun and talkative. They have a cool style of living, everything is in great shape, very clean and the bed is comfy. The location of the apartment is excellent, in the heart of Prenzlauer Berg.
However, and this is not meant pejoratively at all but is only a fair warning for light sleepers like myself: pack some earplugs. There's the main street in front of the windows as well as a fridge inside the room. Might get a little noisy.
