After having arrived at the Changi Airport with our long layover, we decided to stay at Aerotel Transit Hotel (T3). You get an option to book a room for 6 or 12 hours.
The room was super cozy with a private bathroom. We had booked the room for 6 hours.The breakfast was complimentary, was indeed quite satisfying and the view was just the cherry on top!
The main lounge has a small library with a hand-picked selection of authors.
If you want to choose to indulge, then they also have an open-air pool and a gym for which you need to pay additionally.
