Guests are required to wear swimming costumes while in the pool zone (topless costumes are allowed), and are requested to wear pool sandals (although these are not obligatory). An exception is constituted by “sauna evenings”, when guests are requested to wear towels only (without swimming costumes) in the entire pool and sauna zones. The sauna zone is a ‘no synthetic textiles’ zone, and entrance is permitted only with a towel made of 100% cotton (without a swimming costume). Swimming costumes may be left in the lockers provided for that purpose in the changing rooms before entering the sauna zone. Guests may request plastic bags from the Reception to avoid getting their street clothes wet. On Fridays, Saturdays from 21:00 to 01:00 and Sundays from 21:00 to 0:00 the entire premises are a textile-free zone.
