I’ve consolidated the places I would recommend from my trips to South Korea here with everything I loved, didn’t love and would suggest.
Incheon
Grand Hyatt Incheon
208 Yeongjonghaeannam-ro 321beon-gil, Jung-gu, Incheon, South Korea
Loved the modern design, the location near the airport for a quick layover, a large room, and amazing breakfast buffet
Didn’t love that the wifi was slow and hard to connect to at times
Know that there is a free shuttle but if you arrive after 10pm, you’ll need to take a taxi for about 20,000 won
Seoul
Best Western Premier | Hotel Kukdo
164 Eulji-ro, Jung District, Seoul, South Korea
Loved the easy check in, modern large rooms, beautiful views out over Seoul, and good prices
Didn’t love that the hotel probably will need an update in the coming years
Know that it’s easy to explore Seoul on foot or subsway from this location
