Berlin was never on my Europe list but I happened to visit it in April 2015 (whoa 3 years already!) when I was pursuing a course in Rotterdam. Berlin had to be on the list, thanks to the best friend living there, who promised to host me (yaay!). I was on a tight schedule of 3 days and shoe string budget as it was the last city of my European travel. I had exhausted most of my Euros and wanted to make most of the free things to do in Berlin like a budget traveler.
