The winger is on-loan with the Viola from Leeds United, having arrived in January.
He told Four Four Two: "There are a lot of positive things here, Viola Park really has everything you need. A bit like the centers of Manchester City and Tottenham, it's a joy to experience.
"And the day before the match we have a retreat: in the Italian style, you spend a lot of time there, together, in the hotel rooms. This usually leads to complaints in England, but for me it's a pleasure.
"There's a spa, in this climate you can drink an excellent coffee in the open air. And the pitches are perfect."
On his future, Harrison added: "Coming here has opened my mind to many possibilities. The important thing is to be able to adapt to everything and always seek happiness.
"This is my key, to being able to play at my best. Many players are approaching 30 and think they're getting old, but I look at (Luka) Modric and his 40 years: he's incredible. And who knows what could happen to me in the next ten years? I'll give it my all anyway."
