The Cameroon midfielder made the move to Camp Nou from the Gunners this summer, and says that former team-mate Cesc Fabregas helped him settle in
The Cameroon international called time on a six-year spell in north London in August, and has since made 17 appearances for the Blaugrana in all competitions, scoring one goal in the process.
"I feel fully adapted at Barcelona, where people have received me very well," he told Le 10 Sport.
"I live in the house where Thierry Henry used to live when he was here, and I can see Camp Nou from here - it's great.
"I feel grateful to Cesc [Fabregas], who has helped me a lot since I arrived. He gave me good advice."
Song went on to say that he supported Paris Saint-Germain as a boy, but is in no hurry to move to the French capital.
"My team in Ligue 1 is PSG and of course I would like to play for them, but they're very far from me now. I have signed with Barcelona for the next five years, and I am very happy now."
