I would recommend this place if you are looking for a cheap and clean place to stay. If you don't mind sleeping with other people in the same room, then book this hotel.
You have your own lockers and nearby charging ports near your bunk bed. Also, the airport MRT will take you directly to this place. You just need to walk about 5-10 minutes from exit 7 at main station. They will give you directions so don't worry.
