Södermalm or Söder as the locals say are one of the most trendy and popular parts of Stockholm. Stroll around from vintage stores to cafés, bars and museums and just enjoy! Södermalm is not big, depending on your schedule you can walk everywhere, it is about 10 km all around Söder, there is also multiple buss lines and subway stations on the island. Go for pub crawl in Hornstull, visit all the amazing shops in SOFO, specifically around Nytorget and don't forget to visit Fotografiska, the museum of photography.
