This is a summer only spot, and it's known that Swedes go crazy during the summer! It's a terrace, located in the otherwise dull quarters behind central station. Great DJs playing mostly urban music and great vibes all around, it's a true summer classic in Stockholm.
If you're lucky, you happen to be in Stockholm during the short period when the weather is nice and the sun really never goes down. Being outside on a terrace, around beautiful people dancing it out to bass heavy music is a great way to see Stockholmers on their best behavior.
Go here on a weekday if you don't enjoy queuing.
