Seoul is a pleasant city where it is good to live. You do not feel the spirit of a capital or a huge megalopolis. People are welcoming. The culinary traditions are tasty. The temples and historical sites have their charm. The transportation is easy to use. The city is scattered, so it's not easy to visit. You have to plan to visit district by district. The Seodaemun Prison is an incredible museum. N-Seoul Tower is one of the spot to visit if you want to have a large view of the city. It's better to reach it by walk across the mountain.
