The location was difficult to find at the first time. Get the elevator at Gate 22 on Departure floor at Terminal 2, and go to 5th floor. SOUTH side of 5th floor, not north (they're pretty apart). The transportation between Terminate1 and 2 is also very convenient with Skytrain, even midnight.
Facilities are not bad. Very clean and dyson's hair dryers as for lady's showers. There is no hair dryer in male showers, careful. Comfortable bed and enough space. Just a mirror inside the room. There were some books about travels we can read.
The staff speak English and no problems to communicate. Not so friendly but also not brusque :)
