Short city break - Amsterdam, Copenhagen or...

[Dibble]

Finally I've got rid of my loan, which means I'm now going to have a few hundred quid at the end of every month to spend on "stuff". During the time I've been repaying the loan, the holidays have been a bit thin on the ground.

So now I'd like to do some weekend/short trips with Mrs Dibble. I've visited Amsterdam, Normandy, Gothenburg, Oslo and Stockholm myself previously, so I'm after some suggestions for 3-4 days with enough variety to keep us entertained.

So somewhere with a few decent bars, shops, restaurants, museums, galleries and "sights", preferably all "doable" on foot. Budget will be about £500-600 for both of us (I'm paying!).

Europe preferably, within 3-5 hours of the UK.

Thanks for the suggestions so far. Plenty to have a look at.
