Irene's flat is really a good place. Less than 10 min from the train station, 2 min from the tram station. The flat is suitable for both business and tourism : quick internet connection, easy access to the public transportation and 15 to 20 min walking from any touristic place in Florence.
Irène was always easy to reach and was really eager to help : thanks for that!
I really see no bad point on this stay. I strongly recommend !
