I must admit that I was a bit skeptical of my fellow reviewers who cautioned about the size of the rooms. But they were right. This was definitely the smallest twin room I've ever encountered (even in Japan). The space constraints are a legitimate burden if you're not a light packer. The small hill to approach the hotel entrance also mentioned by reviewers was far less of an issue. I've attached a pic from Exit 10 to offer perspective. On positive notes, the beds were comfortable, the bathroom had ample space, and the hotel was immaculate writ large. And I have to highlight this property's two greatest attributes: location and price. The former makes it ideal for anyone wishing to take either the metro or express trains to either of Seoul's international airports. It's also convenient as a hub for regional travel and for shopping at Seoul Station's Lotte Mart/Outlets - both easily accessible via the metro underpass.
*Tip: To avoid schlepping your luggage up the stairs when exiting the metro (Exit 10), exit through the SCT Mall, which offers both escalator/elevators. Pic attached.
