Santon joined Newcastle from Inter Milan last summer, and has nailed down a first-team spot after a tricky transition period.
The Italian international told The Independant: "Last season, the first few months were difficult for me because Serie A and the Premier League is totally different.
"But now I feel better on the pitch and more confident, so I am enjoying it.
"I am really enjoying it. I like Newcastle, I like the city and the people in it.
"The fans are brilliant, I like my team and I like the manager. Better than this is impossible."
Newcastle continue their Premier League campaign with an away match against Everton on Monday, September 17.
