Prós: Very convenient for going to lotte world. But that only really needs one day. Easy access to subway.
Contras: Lobby lounge is a joke $25 for a glass of wine, way over priced, even considering korean inflated wine prices.
Rooms don't feel 5-star, a bit small and could use a more thorough updating. Perhaps some plugs near the bed for cellphone charging.
Contras: They said the offered WiFi but I was never able to connect to it. There were no directions (not even in Korean) to show how to connect. There was also a computer in the room that I couldn't use for the same reason.
