Great area on the shore of Kungsholmen in Stockholm, just a couple of stops from the city centre on the tube . Ideal for a swim or summer (or winter for that matter) barbecue with friends.
A huge flee market that occures two times a year, once in spring the other in the fall. Take the subway to Solna centrum and take the 3 min walk to the big sports arena where the fleemarket is held. There is lots of retro and vintage and a good potential of finding bargains.
