If I had to describe my stay in Stockholm with a few words, I could only say: gray and freezing cold!
Still, Stockholm is a beautiful city. However, it would have been even more beautiful if the weather had been nicer.
I really enjoyed the Vasa Museum, where the 17th century warship Vasa is on display. It sunk on its maiden voyage in 1628, and was finally salvaged 333 years later.
