You can cancel up to 12 hours before class without penalty. Cancelling within 12 hours counts as a late cancellation, and your credit will be lost (a penalty fee may also apply).
There’s a towel service in the studio, so you don’t need to bring your own towel. If you’d like to use a locker, you’ll need a padlock — bring your own or buy one on-site. Valuables should not be left in the studio itself. If you’ve booked a PILAT3S session, grip socks are required.
