Cristina and Gianni's place is a lovely place to stay in Florence. Its a clean, well-equipped home with the advantage of a good location and utility shops nearby. Bus stop is just 2 minutes walk and center (Cathedral, Uffizi Gallery, etc being a 20 minute walk from the home).
Cristina helped us thoroughly to book a one-day tour to Siena and suggested good places to eat and see around which was really helpful for us.
Overall, we would highly recommend this place.
Thanks!
