The meals were absolutely delicious, reflecting the chefs' dedication to crafting flavorful dishes, especially with local ingredients. The warm and accommodating staff made me feel at home throughout my stay. However, while the spa services were great, I did find some areas could use a little extra attention to detail, especially regarding the breakfast options.
