The pool. Heated outdoor pool, advertised as usable year-round, even in autumn and winter. The villa also has two bathrooms with whirlpool baths and an open-air tub.
The hot tub. Whirlpool baths in two of the bathrooms.
I haven't yet found guest reviews that mention the water temperature.
Guide's tip. The villa is outside town, so you'll need a car. Get the pool temperature confirmed before a winter stay.
