We left Iitti at 4 .a.m.,and took the bus to Helsinki-Vantaa -airport. After that we got on a plane, and we flew 'bout one and a half hours to Berlin. We hopped on a bus again, and travelled from the Berlin-Tegel -airport to the main railwaystation (Hauptbahnhof).
There we had a few hours to spent before our train to Poznan left on the afternoon. Some of us went to see a tiny bit of Berlin (e.g. the Brandenburger marketplace and the Reichstag building). The others decided just to take it easy and rest a bit at the railwaystation.
At 13.37 our journey's final part began when we hopped onto the train to Poznan. For our surprise the German group travelled with us in the same train. :) After 3 hours in the train we finally arrived to Poznans railwaystation, from where our hosts picked us up. The adventure had begun. My host family was extremely kind and obliging straight from the beginning, so big thank you to them! ^^
