I absolutely loved my stay at David's apartment. It was located only steps away from the Piazza where many works of art, including Michelangelo's David (perfect replica - moved the original to a museum) are open for all the enjoy. His apt is off a quiet residential street that has Chanel and the Piazza on one end and Del Nero and their amazing meat and cheese shops on the other.
His uncle greeted me and checked in on my comfort during my stay. I strongly recommend you consider it if you are a couple or a couple with a small child. Perfect.
