Not so great
Tried at the Expo2020 health & wellness centre. Though the bookings on the app might be good, the one in actual may be a problem. Sometimes they cancel the booking citing a reason but it only comes as a notification and vanishes by the time one can read the whole thing. There’s no email sent for the cancellations from their end. When you’re playing badminton, you might just find some other guys playing volleyball on the side and the ball might just hit you. There’s just waiting for you to vacate the court.
