First time in Seoul and I blindly trusted the Expedia reviews, however I'm glad I did.
The location is conveniently located, a bit long but totally manageable walking distance to the south /honoring of priperty gate and Seoul station. The room is on the small side but very clean. The breakfast is one of the most elaborated in any hotel chain with both Asian and western options, some are healthy as well. I booked higher floor and view was wonderful.
There are two suggestions/recommendations:
1. The duvet could be much thinner for the heating setting, it can be unbearable hot for some guests. I was very lucky the reception went out of her way to find a thin blanket for me.
2. The electric outlet were weird, they force pop out the plug I brought, I had to get creative to keep the plug inside the sockets.
All in all, highly recommend!
