The 25-year-old joined QPR from Spanish giants Real Madrid on a four-year contract in August and has scored one goal in seven Premier League appearances so far.
This is the first time that Granero is playing outside his home country of Spain and he insists that he is enjoying every moment of it.
"I have been here for two months and I am very happy at a personal and professional level," he told Marca. "I am also very happy with the team.
"This is another world and the change has injected me with more energy and enthusiasm.
"I want to experience new sensations. This is an experience that will help me grow in every way. I want to enjoy this city and also face the challenge that it poses."
