It was really fantastic staying at Daniela's House(APT) for my family(esp my 11yrs old daughter)
Facilities was perfect, location is good for calm and rest(only 15minutes to Duomo).
We can go to big Mart(coop) near the APT.
About Daniela... She is so cool and quick response for us. And knows well with neighbor hood.
If you wanna expect private staying in Florence and then choose Daniela House
