We stayed at the Grand Hotel Sitea. It is a lovely hotel, in a great location and a wonderful breakfast and staff. We would stay there again.
We went to the Museo Egizio (Egyptian museum), the Museo Reali (the palace), and the Royal Library. I went to the Decorative Arts Museum while my spouse went to the Automobile Museum. We enjoyed all of them and on a future visit, we would try to see more including the Museo del Nazionale del Cinema which is in a magnificent building.
We very much enjoyed walking around the central city, lingering in the piazzas, and appreciating that it was not crowded with tourists; we were warmly welcomed everywhere. We walked a bit further to go to Peyrano Chocolatier.
We found several nice places to eat including across the street from our hotel, Diecicento; La Piola Sabauda (close to our hotel); Baratti & Milano; Cafe Mulassano; Ristorante Consorzia. Recommendations that we didn’t get to include Magazzino 52 and Tre Galline. We had casual meals at Eataly and the restaurant attached to the Rinascente store. Bicerin is a famous beverage there. The market at Porta Pallazzo is huge. And the gelato at Alberto Marchetti was sublime. There are many exceptional spots for coffee and chocolates to buy. Two sources I used for food and beverage ideas were Rome based Elizabeth Minchilli (she has a food guide for there) and Torino based Mimi Thorisson.
