I am in the hotel now. Very bare basics room, no actual work desk, but there is a two-seater round coffee table.
Comfortable bed, room is quiet enough (25th floor), adequate shower pressure.
Wifi good, breakfast buffet ( in lieu of 500 points) certainly sufficient.
I came in by train/subway, but will go back to ICN by bus since I have found the 6015 bus stop a block away from the hotel.
I think of the 3 choices, bus will be easiest.
I came from the airport via the AREX Express train to Seoul station, then transferred to Subway line 1 for one station,
then transferred to line 2 for 2 stations. The alternative is the all-stop rail train to Hongik University, then transfer to Line 2.
