My wife and 2 daughters stayed at Vittoria's lovely apartment in Florence in June 2015. I was excited to meet Vittoria given the glowing things said about her in other reviews. She was as sweet and helpful as anyone could want, from showing us around her flat, having a pitcher of cold mint and lemon flavored water ready for us upon arrival, and taking us on a tour of the neighborhood. She had also placed instructions on appliances, had restaurant info and a city map for us, and even had a little sign near the shower telling us to watch our step. Her English is impeccable ( she is a college professor at an American University) and her knowledge of the area was impressive.
Her apartment is located only a 5 minute walk to the Ponte Vecchia, and a 10-15 minute walk to the Duomo. Another 10 minutes will get you to the d'Accademia and Michelangelo's "David". A supermarket, numerous wonderful restaurants, and gelato shops surround her flat. There is a very steep series of steps that you have to ascend to get to her apartment from the main road, and I suspect it might be tough climbing for some. Also, there is no air conditioning, but ceiling fans in every room kept the place relatively cool.
My family and I loved Vittoria, and if we return to Florence, would HAVE to stay at her place again.
