Between colony gardens in Amager lies one of my favourite local spots: Baghaven. Good food and cosiness is in the forefront. Various events with and without music gather people on the square at Diamantgangen 75. A very local experience. Great for families, children, young and old.
As the summer is my favorite time of the year and that the beach is just 15 min bikeride away, I recommend Amager strand. Full of people usually though, but even so it gives a bit of an exotic touch to such a scandinavian city with the sea and the bright sand in the hot summer days.
Assistens Cemetery is one of the only cemeteries in the center of Copenhagen and beside from being a beautiful calm place to hang out, sunbathing and having a picnic, it is the final resting place for many great people through times. H.C Andersen, Søren Kirkegaard, Niels Bohr, Henry Heerup is just a few of them.
A lovely co-working space & café, in my favourite neighbourhood in Copenhagen. The community here is warm & welcoming, and the space itself is a dream. Hardwood floors, dusted gem-tone walls, designer furniture, Depanneur coffee, and great lighting in a period building. If you're freelancing within the city for the long-term, or for the short — I'd wholly recommend having a visit.
