At a cost of about £150 a night you do expect a fairly good standard of service. The hotel is well located in Gangnam, and is on the KAL bus route to the airport. This makes it a sensible choice. But the price is extortionate for what you get as an overall package. There are no extras at all in the room, not even a toothbrush!
You do get a reasonable breakfast. That is the only good thing I can say of this overpriced and underwhelming hotel. Try to avoid it if possible.
