Star Service "The revamped spa is an excellent facility, but before you dive in, take note that, with the exception of the complimentary 24-hour gym, there is a daily access fee (US$25 daily, double that on the weekend)"
Jetsetter "You're sure to appreciate the recreational amenities, including a sauna and a fitness center"
