If you want to find out what a country is really like don't go to their biggest city. England is a case in point here. I'd really hate it if people thought that we were all as friendly and outgoing as the sort of folk you find on the tube in London...
Some time back we had a really enjoyable time in Brno, which is not the largest city in the Czech Republic, but turned out to be a super nice place to visit.
When we were planning a trip to Sweden we discovered Malmö, which is the third largest city in the country. So we went there. Although, because of it's proximity to Copenhagen, we also ended up going to Denmark as well.
Malmö is lovely. We didn't quite know what to expect, although it seemed to have a goodly quotient of museums and parks and stuff from our explorations on the internets. We we didn't spot was the Kings Gardens, which is just fabulous.
There's even a windmill, and displays that by early September are probably slightly past their best, but still stunning.
Oh, and in travel writer mode: "The roots of the name Malmo is the phrase "pile of sand" and the 2013 Eurovision Song Contest Final was held in the city. The UK did not win this competition, scoring 23 points and coming 19th".
