I loved it, the food is amazing, there is so much to do, and there is a great mix of culture and modern luxury.
You should really go to Namsan tower for the view of the city it’s best at night, see the cherry blossoms in the right season, hang around Han river and eat chicken there, have fun at the pc bangs and the big malls anyway there is anything you want there ! And the food is amazing !! Try as much as you can to eat local food, you won’t be disappointed!
I’m from korea- if you are foodie, love some trendy clothings- you will love Korea
Absolutely amazing for any ages, travelling around is dirt cheap and everyone is friendly
