The pool. Covered indoor pool advertised as heated, open access, with a counter-current swim system; jacuzzi in the spa.
The hot tub. Jacuzzi in the spa.
One guest describes a good-sized pool fitted with a counter-current swim jet. Booking.com gives 8.1/10 (191 reviews) for the hotel and 8.7/10 (210 reviews) for the residence. I haven't yet found guest reviews that mention the water temperature.
Guide's tip. The pool hours are posted on site: check them as soon as you arrive.
