The closest city I've been to that I can compare Seoul with would be Japan (and even then they are vastly different cities), which I absolutely loved as well. Seoul is a place I would definitely return to, and highly recommend anyone visiting, but for now hopefully you can enjoy it through some of my photos (and I can reminisce). Stay tuned for my take on Thailand!
