Turin runs from the Savoy palaces of Piazza Castello down to the Po and the hills beyond it. Via Roma is the street for museums and arcades on foot. Stay at Porta Susa if you’re arriving by rail, or in San Salvario to have restaurants on your street.
Palazzo Madama, the Royal Palace and the streets of the historic center all meet at Piazza Castello. Via Roma leads south through Piazza San Carlo to Porta Nuova. The Egyptian Museum is just off this route, and the Mole Antonelliana and National Cinema Museum are east toward Vanchiglia.
The Quadrilatero Romano and nearby Porta Palazzo are good for market mornings and dinner in the old streets. The center is walkable, but a room over a busy restaurant lane can be noisy late at night. Porta Susa has the station and Metro Line 1, which helps with an early departure or a trip west along Corso Francia.
South of Porta Nuova, San Salvario sits between Via Nizza and Parco del Valentino on the Po. Its bars and restaurants mean you can eat near the hotel. Lingotto is farther south on Metro Line 1, near the Automobile Museum and the converted Fiat factory. Stay there for those two, not if you’ll be walking to Piazza Castello every day.
Long walks under the arcades and along the river are easiest in spring and early autumn. Summer afternoons at Caselle average in the low 80s °F, and winter mornings are much colder. Porta Nuova and Porta Susa are separate stops, so book near the one your train uses.
