Shelvey joined the Magpies from Premier League rivals Swansea in a £12million deal.
The former Liverpool midfielder made his Newcastle debut in the 2-1 win over West Ham yesterday.
“It’s an easy place to come and play football, to be honest with you,” Shelvey told nufcTV. “The fans are behind you, there are some tremendous players in that dressing room.
“It normally takes a little bit of time for players to settle, but I felt right at home.
“The players were reading my passes very well and people were getting into position, so it was just easy. I thought it would be a lot harder than it has been this week, but it has been perfect.”
