West is planning to marry Kim in the city on May 24.
Explaining his love for the city and why it was chosen to host the couple's wedding, West told Florence's La Nazione newspaper that he adores Florence and loves the Italian lifestyle, reported Digital Spy.
"To tell you the truth, I already came to the banks of the Arno river with Kim last year, just the two of us, incognito," he said.
"I think that our daughter North was conceived here among the Renaissance masterpieces. It was our first honeymoon. It is one of the most beautiful cities in the world-for me the most beautiful in Europe."
The couple are paying a reported 300,000 euros to hold their wedding at the historical venue. It was designed by Don Giovanni de' Medici along the Arno River.
