Castello Dal Pozzo is a lovely historical property on lovely grounds. We were given an upgraded room and sparkling wine on arrival. However, the quaint room in the tower had problems with the air conditioning/heating system. It was not working correctly (no cooling on first night, but system gurgled so loudly that it sounded like a waterfall); when we informed staff the next day, they tried to fix it, but when we returned in the evening it was instead blowing hot air and still gurgling a loudly as before - room temp was up to 26C and climbing on warm May evening. We ended up asking staff to turn off the system, which stopped the hot air from blowing, but did not stop the noise. We slept with windows open both nights, but stink bugs flew in by the many dozens.
