If you haven´t been to Oslo yet, Grunnerløkka is the hipsters´arena. It´s a former working class area where most of the old buildings have survived and make for a pretty quaint atmosphere.The constant flux of young people, Sunday open shops and the Sunday market in Birkelunden keep the area bustling even when the rest of the town is dormant. The borough has lots of nice eateries, coffee shops and shops and it´s always ready for a new wave of people. Long way to go to achieve any Berlin status, but cool is in order. Although a bit too fussy for me to live in, I enjoy taking a day trip to its stores and have lunch nearby.
