I enjoyed my stay at Cristian's house! He was very responsive and helpful answering my all questions and gave me a small guide book on Florence and Tuscany also (which I forgot to leave behind when I left, and Cristian graciously gave it to me as a present). the apartment is very clean and 7-15 minutes walk to all the major sites. there was some noise from pedestrians passing by on weekend nights, but was quiet during week days.
