The two clubs agreed on a deal for the 31-year-old earlier this week, with the former Valencia star heading to Florence on Thursday to complete a medical with La Viola and sign a three-year deal with his new club.
Joaquin, who has spent his entire career in La Liga to date, could barely contain his delight at the prospect of plying his trade in Italy's top flight.
"Serie A has always attracted me," he told Radio Blu. "I waited a long time to play in Italy; it will be a good experience. I know Borja Valero and Guiseppe Rossi, who is an extraordinary player. I'm very happy to come here.
"Eduardo Macia, technical director at Fiorentina, has spoken length to me about how football is played here. It is a philosophy which I embrace. I've reached a good moment in my career and hope to exploit it here."
Speculation has linked Bayern Munich forward Mario Gomez with a move to Florence of late, and Joaquin feels the Germany international would be a great addition to the squad at Stadio Artemio Franchi.
"He would be a great buy. He's a very strong forward," Joaquin said.
