I don't know what a host needs to do to become a "superhost". However, in my book, Daniele is such a host.
Before we even arrived, Daniele helped us by procuring a phone and information for the best SIM card to use in Italy and for us to call the U.S.
When we arrived, he was waiting to welcome us. A bowl of fruit from his orchard was sitting upon the table. After giving us a tour of the house, he gave us a tour of our environment--ATM, grocery store, open market, cultural places of interest.
Whenever we had a question, he answered us immediately and with helpful advice. Whenever we needed advice, he was available with suggestions. He did everything that we would have expected from a "superhost" and MORE.
