We shared the apartment with Marion, a very nice and welcoming guy. He recommended us some places in Berlin to visit in. The pictures on Airbnb present exactly what you receive. The neighbors were pleasant, some of them German and others migrants. The way to the building from Alexanderplatz is it not so easy to memorize... it is take 1-2 days to get use to it. By walking is it 15 min to the Alexanderplatz.
