The best area to stay in Cagliari is the Castello district, offering an elevated perspective of the city and its historical charm.Castello is Cagliari's historic heart, perched on a hill with narrow, winding streets and ancient walls. You'll find landmarks like the Cagliari Cathedral and the Bastione di Saint Remy, which offers panoramic views of the city and the Gulf of Cagliari. It's a very walkable area, though be prepared for some inclines.For couples, Castello is an excellent choice. Its romantic lanes, historic architecture, and abundance of small, intimate restaurants make it superb for evening strolls and enjoying the local cuisine. The views from many hotels and viewpoints are particularly memorable.Alternatively, for those who prefer to be closer to the harbour and the main shopping streets, the Marina district is a great option. This area is flat and bustling, with many seafood restaurants and easy access to the ferries for day trips.
