Having had the pleasure of visiting Finland, Sweden, Denmark, and Norway I have to say I definitely underrated them for a long time. I had a great time exploring the cities with their public transportation and since all the capital cities are ports you can take ferries to nearby islands without paying extra. Their museums were also topnotch and the nearby landscapes are absolute beautiful with some world class hiking in the outer regions. My biggest complaints would be the food, yes the best restaurants were good but I was constantly spending $20+ just to sit down and eat some pasta, even kebabs were minimum $15. That said I highly recommend people to visit them in the summer or fall if you get the chance.
