The Mandarin Oriental Singapore is probably one of the nicest hotels I’ve stayed at. This was my second visit, and once again, the staff were extremely friendly and helpful. The location is also excellent - easily accessible from the airport, and if you’re comfortable using public transportation, you can walk through the shopping malls and convention centre behind the hotel to reach a subway station.
One of the highlights for me was the pool—having an evening swim while enjoying the stunning view over the Marina was incredibly relaxing.
