Nice city to visit for a day or two.
I am a single traveller that was Interalilng around Europe. I heard that Stockholm was a nice place to visit which it was, however, I did find if your on a budget it can be a little boring and very pricey. I also found that you could see the centre of it all in one day and I didn't feel that it offered as much as other European cities that I visited.
Insider Tip:Buy a 72 hour travel card even if you're travelling for 48 as they don't provide a 48 hour one. The next one below is a 24 hour one, however, works out better value for money with the 72 hour one.
