I've been there quite a few times, my pal used to live there.
And as the others say, there's no punting.
Seeking or something like that would probably be much better.
Swedish girls are difficult to pull, they have quite an old fashioned attitude, just going up to them and trying to chat them up can be seen as you being a lecher. Even the drunk ones on Stureplan or in Gamla Stan.
If not using seeking, then it's better if you have someone there who you know who can organise for you to meet / introduce you to girls.
But maybe things may have changed since I last went there 10 or so years ago

Everyone speaks perfect English, so that's a bonus.
