"This was a one night transit stay for us when we were flying through ICN airport.
Room was decent sized with a big, comfortable bed, wifi, fridge. Big shower, but toilet was a bit tight to the door. Comfy chair, small desk, nice raised shelf to put 2 bags up off the floor. Good bedside lighting and outlets. A couple of bottles of drinking water provided.
There is a free shuttle bus to/from the airport that can be arranged in advance, but it does not run 24/7. An alternative, which we used, was a quick (<10 minute), 2 stop, ride on the AREX train (you'll need a T-Money card to ride the train). Once off the train exit door #1 and the hotel is a 2 minute walk to the left as you exit the station. It can be a bit difficult to see the hotel name on the building among all the visual signage clutter on the buildings. There are also several hotels in the same multi-story building.
Check-in was quick and easy with english speaking staff.
There is a nice green space, with walking trails, a short walk away. The area has many other hotels, mini-marts and restaurants in the blocks surrounding the hotel.
Our room rate included breakfast. Breakfast was buffet style and had four long tables with just about any type of breakfast food you could imagine from Asian to European.
We'd happily stay here again."
