My friend and I traveled to Berlin for the weekend to participate in a festival and we really enjoyed staying at Ahmad's place. The room, bathroom, kitchen, and living room are spacious and comfortable, with everything you may need. Ahmad was very kind and friendly. You can indeed smell a bit of smoking in the common areas as some of the other reviews mentioned, but it was not enough to stick to any of my clothes and the room we stayed in didn't smell of smoke. Overall, we have nothing to complain about :-)
