Emir is very nice : even if he "hosted" me in his flat when he wasn't in Berlin, we met in Paris 2 days before, and he gave me all the practical informations I needed. That was very nice.
When we arrived in berlin, belong to his explanation, it was easy to find. My girlfriend and me where nicely welcomed by the other airbnb roomate :-) The flat is beautifull, and big. Everything was clean, safe, working well. We arrived late in the evening, and we could find where to drink nearby. (To eat, we went untill Wurst 36, near to the Zoo, after walking 30 min). This area is quiet and beautifull. If you are tourist, you are near to Charlotenburg castle, Postdamer Platz and the Zoo : beautifull and rich places. To go until Brandeburg Tor, Unter de Linden avenue, the museum island, East berlin or Kreuzberg, you need to take the subway, which is very efficient in Berlin. Just too far when you decide to discover this big town by bicycle... So, I recommand Amir, and his flat. With pleasure to see you again !
