I was there in April as well. I liked the hotel very much. I wished there was a restaurant, but everything else was great.
Apparently there are signs pointing to the hotel, but I missed them, and walked outside through the parking lot, and on the street.
To get to the hotel from the terminal, just go to the green city-train corridor, and instead of turning left and down to the platforms, keep on walking straight through the long tunnel with moving walkways. The end of the tunnel exit is by the hotel.
