Mourinho led Roma to a first European trophy last season with the Europa Conference League.
“I always say that training grounds are the same all over the world and the lifestyle is always the same, you go in at 7.30am and you leave at 6.30pm," Mourinho told Esquire Italia magazine.
“So in that sense, it changes little whether you are living in an incredible city like Rome or a cold, dark and hidden away place. What changed in my life is that I am happy at this club and get along with everyone. I do feel happy in Italy."
This year, Mourinho had tattoo done of all the three UEFA trophies he has won.
“It was truly unforgettable. When we won the Champions League with Inter, I didn't go to Milan because I wanted to join Real Madrid and felt that if I went back there, I would not be able to leave again.
“This time was different, I wanted to remain at Roma and continue with this club. At those moments, you realise that you don't win for yourself, it's not a personal joy. The people are everything, they show you what you've achieved and make you feel part of a truly special family.
“I had promised that tattoo to everyone, a tattoo only I could have: all three European Cups won. I could get another tattoo if my children were to have kids, that'd be a special way to celebrate it, but no more football-related tattoos."
