I was a former member of Spectrum/ Bay Club Howard Hughes (Closed). When Bay Club took over that spot I think they improved it. The SM club isn't bad by any means. It's like a step up from the LA Fitness/ 24 hour fitness- maybe close to equal with those gym's highest service level- but way more expensive.
They offer complimentary coffee, have good towels which is nice. Limited and dated cardio equipment here.
As others will state, it's a weird layout but not necessarily a bad one. The equipment is pretty decent.
Parking is great and easy. It's relatively clean but the locker room is small and really stinks. Something I really found pleasant about Equinox is the top-notch cleanliness (including locker rooms, showers, etc- but of course you pay for that)
Honestly I feel the dues are about 25% overpriced at BayClub.
