The exact official treatment timetable is 08:30–20:00, seven days a week. Advance booking is recommended and arrival is requested 15 minutes before the appointment; lateness shortens the session.

Expectant-mother care is offered after the first trimester, and health conditions, allergies or injuries should be disclosed. The spa is mobile-phone, pager, alcohol and smoke free.
