Explanation:

1. Add a comma after "Italy" to separate the introductory clause from the subsequent action.
2. Add a comma after "Spain" to create the required serial comma (since serial commas are mandatory here) for the list of countries.
3. Confirm the existing comma after "Portugal" is kept as part of the serial list, and the comma after "Florence" stays for the city-country pair, resulting in 4 total commas.
