Due to a change of flight schedule, I had to spontaneously book.a night's stay at Incheon, for which I chose Ibis Styles. There's free shuttle bus from T1, which runs every 1 hour (a bit too long I think) and takes about 15 - 20 mins. I also took the shuttle bus from hotel to T2 for dinner, which runs every 30mins and takes abut 5 - 7 mins to arrive. The hotel room looks and feels very new, neat and tidy. I particularly like the separate shower and toilet arrangement, but there's no door to the bathroom? Last but not least, it can be quite noisy at times due to airplanes landing, but it is inevitable. Overall, I'd recommend this to people who needs to stay a night at Incheon Airport.
