I stayed one month at Susanna's flat and everything was perfect. I had a great time in Florence. The centre of the city was within walking distance so I could explore the city by foot. The room (as well as the whole flat) was charming, clean and cozy and I had everything I needed.
Susanna was the best host I could have had. She is very friendly, welcoming and helpful. It was important to her that I felt comfortable. Also her parents were nice and helfpful whenever they visited us.
I can really recommend the flat and Susanna as a host. I'm glad that I met her and hope to return to Florence someday :)
