Hotel Manu is about 10 mins walk away from Seoul station. we had trouble finding it at first. there was a reviewer who said that it is linked to the station by a bridge and that is true but it is not a short walk. it is outdoor. but we grew to love the bridge, called Seouljo. it's like a garden on a bridge, with many trees along it. it's beautiful. so while it takes about 10 mins (with luggage maybe more than 10), it's very pleasant to walk on that bridge.
BUT, Hotel Manu is very close to Namdaemun market which is great. I get my breakfast there during our stay. and Hoehyeon station exit 5 is right at Namdaemun, which means the hotel is very close to Hoehyeon station, just not Seoul Station.
the room is a very decent size, clean, comfortable. on our first night as we arrived late at night, we had beer and chicken at a restaurant located at the hotel called Soulista and it was very good. I really enjoyed my stay at Hotel Manu. on
