Left Poznan around 10 am and ken the gps said it was a 3.5 hr drive. We really caught him out this time as the Poles have built a new Autostrada since he was programmed so it was only about 2 hrs. We had to turn him off in the end as he kept wanting us to turn around. If we had known we could have done the drive from Warsaw in one day but no bother. Arrived in Berlin and have great apartment in the gay area (apparently) and easy access to U Bahn. Caught UBahn into Alexanderplatz and then onto Hauphbahnhof and bought a Berlin card so we can get free travel on all public transport. Had to have a couple of drinks to work out all the maps we were given. Walked onto Reichstag and Brandenburg gate. I now remember it all but last time it had the wall in front of it. Fantastic to see it as it should always have been. Walked back to Alexanderplatz and caught UBahn home. Stopped for dinner and drinks before returning to apartment.
