I recently completed a 2-night stay at this hotel 2 weeks ago and will be returning there this weekend for another two night stay.
The place is nice. It's actually very nice as I had a comfortable stay with no issues at all. I was even granted a late checkout of 4 PM (left at 2 PM). The outside of the building is being cleaned/repaired/painted. The breakfast at the top floor area was very nice as well. I am unsure if I booked a reservation for the Executive level last time as it was a last minute booking as I wasn't sure I would be traveling into Seoul from Chuncheon. However, this weekend I book the into a non-exec room type. Will be interesting to see if I'm upgraded to the executive level upon checking in.
