Swedish capital city sprawling across 14 islands, with many different vibes.
Surrounded by water and spread across multiple islands, Stockholm is also called “the Venice of the north” or “the Venice of Sweden”. Somewhat similar to Amsterdam (the other “Venice of the north) but whereas Amsterdam is much more compact and dense and with much narrower weblike waterways, Stockholm feels like larger islands with larger bodies of water between them. Stockholm is also cheaper than other Nordic country capital cities.
3 days would be enough to enjoy the main sights. Visiting different islands to check out squares, restaurants, museums, and city views across the water. Also experience varying lifestyles between the busier islands and the quieter ones. Enjoying some nature and landscape. See some interesting architecture in the buildings and metros, perhaps take a boat ride.
