Stockholm has a highly efficient public transportation system. To navigate the city, you can use the metro, buses, trams, and ferries. You can purchase an SL Access card, which provides unlimited access to the entire transportation network for a specified duration.

To start, visit Gamla Stan, the historical heart of Stockholm. You'll find historic cobblestone streets, ancient buildings, charming cafes, and the Stockholm Palace there. Additionally, the Vasa Museum and Skansen are also worth adding to your itinerary for a deep cultural experience.

You should definitely try köttbullar, the typical Swedish meatballs often served with potatoes, gravy, and lingonberry jam. Additionally, if you're feeling adventurous, give surströmming a try, a fermented herring known for its unique aroma but beloved by the locals.

While Stockholm is known for its relatively high prices, you can still find interesting items at more affordable rates in the Södermalm district, especially around Götgatan. If you're into Scandinavian design, the Östermalm area offers various options. For souvenirs, consider purchasing a Dala horse (hand-carved and hand-painted wooden horse) or distinctive Orrefors crystal.

In Stockholm, as in many places in Sweden, punctuality is highly valued. So, if you have an appointment, it's best to arrive on time or even a little early. When using public transportation such as trains or buses, people typically remain calm and maintain their distance; being noisy or talking loudly on the phone can be considered impolite.

When dining at a restaurant or cafe, remember to say "Tack" (thank you) when ordering or receiving food. And while walking in the city, it's advisable to always stay on the right side of the sidewalk or escalator so that those in a hurry can pass on the left.
