Spent three nights here, visiting for a wedding. The wedding was held in the hotel (which is quite common in Korea it appears).
Had a No Smoking room - good standard, clean. The room contained a computer with free internet connection, which was very useful for email/local maps etc.
Breakfast was good. Polite,prompt regisitration and room service.
If you are connecting to/from Incheon Airport the 'Airport Limousine' Bus service is very convenient - takes no more than an hour for 9000 Korean Won. There is a bus stop right next to the hotel.
The nearest subway station is approximately 1km away.
