I had a one-night stay here on business in mid-September 2013. Caveat: this was my first stay at a W hotel, and I'm not sure I 'get'/like what the brand is about. Good Stylish property, great views. Friendly and very enthusiastic staff. Well-designed comfortable rooms. Casino next door. Excellent full breakfast as platinum amenity. Bad No upgrade, no lounge. Basically no platinum recognition beyond the amenity (although the breakfast was a very nice touch). Painfully overpriced minibar/room service. Remote location so no restaurants or shops nearby. Only one small bottle of complimentary water in the room. Overall This is a stylish hotel in a picturesque location but there are much better options for platinum members in Seoul. I probably wouldn't stay here again unless I was looking to spend a lot of time in the casino or had an unlimited budget.
