After the initial request, I never dealt with Cosimo. All my dealings have been with his father Saverio. He was a very nice host. Provided all the information needed and even helped order a taxi back to the airport on our departure day. The apartment couldn't have been located better. Literally steps away from the old bridge and the Uffizi Museum. We walked everywhere. Never a need for a taxi. The apartment itself is also perfect. Spacious comfortable and clean. They provided everything you would need. I would definitely recommend this apt and would stay again next time I'm in Florence.
