I've always wanted to try "The Retreat spa" at Changi village hotel.

After all the procrastinating, I finally tried it last wednesday & i will definitely go back again.

The price range is a tad higher but their good service & wonderful ambience made up for the pinch.

If you do not mind spending a little more i would recommend the private room which comes along with your own private outdoor jacuzzi that faces the sea. That 2 hours rejuvenated my tired soul.
