My wife and I stayed here for five days in April, 2011. While not easily found initially once we were booked in it was easy to find your way around. The hotel is within a 15 minute walk of Namdaemun and a similar walk time to Myeungdong. Restaurants, post offices etc are also within easy walking distance. The secret to staying here is to walkout the front door and turn left. After a short walk along a windy little alley you come out at the Namsan tunnel. Taxis pass by every few seconds and there is a turning bay just up from this pick-up point if you want to go back into Seoul centre.
The rooms themselves were quite roomy and the bathroom was enormous. If I had any complaint it was that cleaning of rooms was not undertaken at a set time - one day it was at about 3pm, another day at about 5pm. I would say that the rooms were generally quite clean.
Desk service was excellent. On several occasions we wanted to go to specific sites and the staff were keen to assist.
While I have read several comments about the limited breakfast choice (eggs, toast, juice, coffee) for the overall cost of the accommodation ($74 - $90, depending on season) who would complain?
Having stayed at 5 other hotels in Seoul I would say that this was great value for money and probably the most central to most sites (including a short walk to Namsan and N-Seoul Tower. Would happily stay again!
