I never said unfriendly, just standoffish well until you drag out your wallet. I also been to all the Scandinavian countries.
I liked Denmark the best, especially in the summer, and have been back several times.
Sweden, which at time I was there, you had to take a ferry but now there is a bridge between Denmark and Sweden, we railroaded up the west coast of Sweden, but is way to expensive to spend much time there, and in Norway (Stavanger) I wanted to see the coastal fyords, however all the time I was there it was too foggy.
In Finland it was so snowy I didn't want to venture out the short time I was there.
Also railroaded (Euro pass) down from Denmark into Germany, Netherlands, Belgium and France across the English channel to England.
Another time after working in Netherlands we went to Paris (third time in Paris) seen all the sites and took the TGV (high speed train and I mean high speed) from Paris to London. (not high speed in the UK.) It's a short drive to any and all London's tourist sites from the train station. But would strongly recommend the Underground rail.
