I went to the Key Tower location.
Wonderful views, nice new equipment, a very nice pool, a helpful and friendly staff, nice locker rooms, good free weights, tons of cardio equip, a free towel service, free parking.
That said, it's just a tough place to get to unless you live in or near downtown. I live in Ballard and the location was just too inconvenient. I appreciated the gym, but having somethign close is key in the motivation of getting there.
Good gym though, overall quite a bargain.
