The airport shuttle bus was just down the road from the hotel, very comfortable and probably faster than the taxi we used to get to the hotel. WiFi was very good. The room was very clean and comfortable. 2 reasons for not giving a full 5* review: lots of things left just inside and outside the hotel entrance for demonstrations because apparently the hotel let go some staff that they felt was not justified. I was also disappointed that I was charged for losing a room key - plastic card that is easily lost and won’t cost the hotel much.

Sejong Hotel has lots to improve.
1) We stayed at a bigger twin room facing Namsan Tower. But what we didnt know is that its also facing the road hence the traffic can be very noisy. Not for light sleepers.
2) There are daily worker strikes at the lobby and the entrance of hotel. The workers feel their dismissal during Covid was unfair hence they have been on strike to have their jobs back since then. I have to salute on their perseverance but aesthetically, not something youd like to be welcomed every day. They start their campaign early morning and again, not for the light sleepers.
3) The hotel is located near the airport limo but as we had many times stayed in hotel located within Myeongdong shopping, we find the location a bit of a walk, especially after a day of sightseeing and shopping so choose whats important to you.
4) Room is big and dated. Expect some mold in bathroom. Bed and pillow too soft for comfort and gave us neck and back ache. You can open the window for ventilation but we called for help to do that as were afraid the window might drop 11 storeys down. Housekeeping not entirely clean.
Overall, Sejong Hotel is more like a big overpriced guesthouse. They might do better if they had employed more people.
