As the largest health club in downtown Rotterdam, this gym is popular with local residents and office workers. Its largesse also affords ample space for a 3-lane x 20-meter lap pool with bottom stripes and floating lines (kickboards and pull-buoys supplied as well). Most equipment is new and high quality. We noted Life Fitness cardio machines, Hammer Strength muscle-pumpers, plenty of free weights etc.
Ambiance is comfortable and inviting. Admission is somewhat pricey at €20/day, but those staying at the Holiday Inn Express get in for half price - €10/day. We walked here from the core of downtown (Hilton/Westin hotels) and it took about 5-10 minutes.
