Johannes and his flatmates are lovely. Even if the appartment is halfway between move and restoration, you will love it. By the way, the price is very interesting for the location which is perfect to discover Neukölln, Kreuzberg, Friedrichshain, the Tempelhof airport etc. and you have several train stations around to be quickly in the other districts of Berlin. You have everything you need in the appartement, there is hot water and heating, etc. The kitchen and bathroom are completely functional. The bed is comfy. But as it is very clearly explained in the description of the appartement, do not be surprised by the "under works" state of the flat. Johannes offered me to use their living room if I wanted to work. I highly recommend this place and its adorable guys.
