Sonia's place is the ideal Italian city stay, and she gave us the warmest and most thorough welcome of any Airbnb host we've had. Sonia ensured we had maps to navigate the neighborhood, details on all the appliances, and even picked up groceries prior to our arrival because she knew we'd be arriving late at night, past closing time.
The place itself is neat and homey. She lived there with family in the past and has left a small book collection including books about Florence and tourist guides. The private terrace is an obvious highlight for reading, snacks, or card games, though watch out for Florence's mosquitos.
As for seeing Florence, walking from Sonia's neighborhood to the city centre is straightforward and the major sights are easily accessible on foot. It's difficult to imagine a better host and apartment. Grazie!
