The Slovakia international has been at the club for over five-and-a-half seasons since signing from Brescia.
Hamsik, 25, has been in fine form this campaign scoring ten goals to help lift Walter Mazzarri's side into second position in the standings.
And the player insists he has no plans to walk away from the Partenopei any time soon.
He told Corriere dello Sport: "I have bought a house in Naples and I feel fine. My family are very happy here.
"I don't want to look too far into the future, but at the present time I am enjoying my life."
