The Argentina captain, who is on the verge of signing a new deal with the club, is settled on Merseyside.
"It's been fantastic and I don't get tired of saying that," he told FIFA.com.
"They've treated my family and I superbly right from day one and we don't have any complaints. Liverpool is a lovely little city too, and it's growing fast.
"It's a port city with a lot of hard-working people and it's grown a lot in the last few years.
"If I had to recommend places for people to visit, I'd say the best-known sights like the Beatles Museum and Anfield. It's a lovely city."
