I feel like the hard product here looks much better in person than it does on the online photos. It definitely feels a step above the other properties in the city I've tried and is aesthetically more attractive than Josun Palace, the other Western points chain "true luxury" brand hotel I have tried.
Of course, properties like Josun Palace, Andaz, and Westin Josun have more around them that's walkable, besides Coex (which, at least for me, has an Egg Drop and a Shake Shack ;-)).
