Public transports are cheap €2 for endless changes during an hour.
Cheapest is strolling around and catching a few worth to see places.
What places you MUST visit:
1. The Old town (There you have the Royal castle for example)
2. Drottninggatan (Shopping spree)
3. Biblioteksgatan (Expensive designer stores/watches)
This is an auction store, and they carry watches at good prices.
4. Gondolen (Restaurant with the best view)
5. Skansen (The world's largest outdoor museum)
To be honest I think you'll find your own favourite places to see.
Night clubs:
1. Café Opera
2. And ALL places at and around Stureplan.
If you need to know anything else, just ask.
AND NO: You CAN'T find any watch replicas!
