If you are looking for a good quality, reasonably priced massage (less than 10€ for one hour) in the center of Jakarta, this is the perfect place ! Everything is in the name : "Clean and healthy". No specific ambiance, but the masseuses are capable and nice. Showers are available before and after the massage. Much better value for money than the international hotels in area.
A drawer with a lock is available to keep your belongings safe.
