Swedish currency is Krona. The Euro is not generally accepted, nor is the US Dollar. Cash is also seldom used, with credit/debit cards being the primary payment method. American Express is not widely accepted in Sweden. Currency exchanges are common, but they will ask for your passport to exchange any currency.

When to go

The best time of year to visit Stockholm is late June into early August. Outside of this rather limited window, the weather can vary greatly. The Christmas season in the city is wonderful, but it will be pitch black dark by 4:00pm in December. In the summer months, expect lows nightly lows around 60F and daily highs around 75F. The spring and fall can have an abundance of rain, though the city does not always have snow in the winter as the Atlantic Gulf Stream ends at Stockholm.

Alcohol

The Swedish government has a monopoly on alcohol sales. Aside from restaurants and bars, any alcohol over 3.5% ABV must be purchased at the government-owned Systembolaget stores. These stores close early on Saturday's and do not open on Sunday's. Grocery stores do not offer beer or wine over 3.5% ABV.

Safety

The Nordic countries are generally some of the safest places on the planet, with Stockholm being no exception. Swedish society is a very rule-based order with limited crime, virtually zero pickpocketing, and very little tourist scams. It's always important to keep your passport secure, and it's ok to limit the amount of cash you carry in Stockholm as cards are so widely accepted.
