Great location near the COEX and the subway. Hotel staff were friendly and most spoke English. Front desk was very helpful to a foreign traveler and wrote down names of places for me to show taxi drivers.
Room itself was clean and as advertised. Suggest specifically asking for a room with internet if that's important to you as otherwise the rooms do not have it.
Diner near lobby is small but standard dining fare with some Western food available.
Prices are reasonable.
