Never trust someone who says they didn’t like Berlin. Seriously, put them straight on your  list of people to keep an eye on. I enjoyed a glorious week there back in April 2013. The place was positively dripping with history, art and the kind of architecture that gets you wet between the legs. My wife and I booked a fancy hotel on Alexanderplatz with absolutely no idea that it would be our final holiday together.  Have a look at my articles on:
Berlin Cathedral (coming soon!)
Charlottenburg Palace
Ramones Museum (coming soon!)
& my choice spots from across the city.
