Over 30% of the town area is made up of waterways, and another 30% is made up of green spaces. Air quality is fourth best of the European capitals – behind Zurich, Copenhagen and Vienna.Despite its northern location, Stockholm has fairly mild temperatures through the entire year.

If you’re into your art and history, this island also boasts many of the capital’s most widely used museums.Stockholm is often described while the “Venice of the north” on account of its setting. Where Venice is claustrophic and crumbling in a achingly romantic way, Stockholm is just a city that lets you breathe; its finest buildings stand proud on open boulevards or teeter on high ridges overlooking the water. There’s a gothic element to a lot of the architecture; more Prague than Paris.There is an acquarium, worth the visit alone for the spectacular waterside views from its café, that will be next to the bustling amusement park, Gröna Lund, where you can defy grafity on tummy-flipping rollercoasters.
