One Friday afternoon in March, I flew to Berlin. I got to my accommodation a lot later than I was hoping - about 10pm. I never seem to factor in enough time for mucking around the airport and transport from airport to city!
The next day, after getting my bearings and picking up breakfast at Alexanderplatz, I hopped on a train to Schloss Charlottenburg. Its a lovely castle that's really easy to get to from the city, and it was well worth the effort.
It also had possibly the most beautiful room I've ever been in - so sorry (but not really...) for all the photos of it!
