Travelers ❤️ these 🏨 after their flight to Singapore

Crowne Plaza Changi Airport by IHG
"The property is beautiful and the perfect place to stay if you have an early or late flight out of Singapore. Just note if you are flying out terminal 4 you will likely need a Grab or taxi to get to the terminal, unless you want to ride the airport train and then transfer to a bus to get there."

"What I like; convenience, staff was helpful. What I don't like; No AC in the certain area, shower was a little old, water was slow. Price a little expensive. Average; for napping, resting couple hour is excellent."
