Abdullah was a fantastic host. He was very accommodating, helpful and friendly. He gave me some superb recommendations on where to visit on weekend, where to go shopping, cafes, public transport, gym, etc. He always took the time to help me out on every occasion. We also enjoyed his very comfortable apartment, which is in the decent location, 10-15 mins by s-bahn to AlexPlaz. If you are in Berlin, you must stay at Abdullah's place in Shoneberg!
