Until recently Google streets has not been availible for Sweden and Denmark. There has been local sites with a similar function, like http://hitta.se/gatubild. But now you can also use Google streets for your virtual tour to Sweden and Denmark. Not only the large cities but also smaller villages and country roads can be seen in Google streets.
To use Google streets go to maps.google.com, find your place of interest, click and hold the little orange man that stands just above the zoom handle and put him down on the street you want to visit. Streets with photos will get blue borders when you lift the little man and you can of course only put him down on such streets.
