Skuse, 23, has played all of his professional career with City, making close to 200 appearances, and he is thrilled at how Harley has settled in at Ashton Gate.
"Hartley is a top man," he said. "Having him around the place really helps a lot.
"He's played in the Champions League, been there and done it, and he's a great lad off the pitch.
"It's great we have been able to attract a player like that. If you'd have said we'd be signing someone like him five or six years ago then you wouldn't have believed it."
