Having just returned from FS Seoul, I can attest to its convenient location, excellent facilities (especially health club/pool and Executive Club Lounge), superb concierge service and inconsistent housekeeping services. As I said in my recent review, service isn't as crisp or proactive as we would have expected of a FS property, but everyone seems to focused on that goal. And, the opening special of W100,000 credit per night towards spa and F&B use makes a stay here a good value.
