Housed in a 15th-century convent, the Four Seasons is miles away from monastic simplicity and austerity, and yet this hotel in the Golden Shopping Triangle of Italy’s fashion capital has managed to retain an aura of tranquility and contemplation. This effect is most pronounced in the rooms that open to the inner courtyard and the cloister. In the lobby you can see original frescoes, and in the bi-level suites you sleep under restored barrel vaults.
