Stockholm is an exceptionally clean, modern, and safe capital city. It is almost entirely a cashless society; ensure you have a contactless credit or debit card, as physical cash is rarely accepted. While violent crime is rare, pickpocketing is a minor issue in major tourist hubs like Gamla Stan, the Central Station (T-Centralen), and on the metro during rush hour. In winter, the primary danger is slipping on packed snow or ice on the city's granite walkways; sensible boots with good grip are vital. While the city is very safe, it is best to avoid lingering in certain suburban areas late at night that have experienced recent issues with organized crime, though these are well away from standard tourist zones.
