Very conveniently located in terminal 2, just follow the signs to the "airport hotel". We did not make reservations and stayed on the day after Chinese New Year. We were so glad they had availability! Upon entering the room I was struck by how clean the bedroom area was, although completely basic... no pictures or wall hangings at all. That's fine, I was just there to sleep. The bathroom was clean with the exception of the shower drain which was full of nasty hair... which made me opt for wearing shower shoes. You can unfortunately hear hallway noise (people talking, opening/closing doors) very clearly and the airport wifi does not reach the rooms. Otherwise, a very comfortable stay. You may also need to know that rooms are rented by 6 hrs, but we added an hour to make 7. Affordable option considering this is Singapore!
