The pool. Indoor pool in the 500 m² spa, advertised as heated by Staycation, with hot tub, sauna and hammam.
The hot tub. Hot tub in the spa.
I haven't yet found guest reviews that mention the water temperature. Staycation shows 9.8/10 from 60 reviews.
Guide's tip. Ask about the spa's opening hours: pool access may be limited to certain time slots.
