A 19th-century mansion at the water’s edge, this five-star hotel by R Collection occupies an idyllic spot, surrounded by extensive gardens. Inside, the Art-Nouveau design building celebrates art concepts and Made in Italy. It has a lake view restaurant and gourmet restaurants, two bars, an outdoor heated swimming pool and a Technogym. Grand Hotel Victoria’s Erre Spa is quite something, with water paths, aroma and chromotherapy, an ice room, Himalayan Salt Room, tropical and waterfalls showers, a Kneipp path and an indoor pool surrounded by four-poster day beds. Rooms are sleek and contemporary, with style nodding to the early 20th century. Some come with balconies, but all have minibars and aircon.
