Raintr33 was a nice experience. I arrived late at night and left early in the morning, simply needing rest during a layover at Changi Int'l Airport. The staff was very kind and helpful, exceptionally so. Note that it is a bit more exposed to natural elements, such that your bathroom sink is outside on a balcony (not enclosed), so I saw a few tiny insects inside my room and also a little insect in the lobby. All of them totally harmless, but just be advised. The location was reasonable for commuting to the airport, but it not badly near downtown. If your goal is to see Chinatown, Merlion Park, Gardens by the Bay, restaurants and shopping, etc, you'll want to look into something downtown.
