K-haus Dongdaemun is a great choice for a stay in Hwanghak-tong. You'll have free perks like WiFi and wired Internet. Nice touches like bathrobes and slippers are offered up in all rooms, along with flat-screen TVs and refrigerators.
Pros: The staff is available all the time. Easy access to floors with elevator.Cons: The hotel staff don't speak English. Location is not that strategic.
