Everything. Great service, bright, clean, well ventilated (none of that 'gym' smell), all the fitness equipment one to ask for, all the equipment looks new and in great condition, nice pool. The sauna was not has hot as I would like but maybe I just don't know how to raise the temperature.
Friendliness of instructors and trainers
Knowledge of instructors and trainers
Cleanliness of entire facility
Background music is played at a lower level so you can still have a conversation or meditate
Variety and choice of exercise classes and equipment to meet many needs
I have greatly benefited from working with my trainer, Sue, for the past 5+ years. She is very knowledgeable and monitors my activities appropriately. And I have also benefited from Tai Chi with Larry...for the past 3+ years.
