Ciao and welcome to our forum!
You won't be disappointed as far as food goes or the quaint villages across the region!
The question is how long will you be here for and will you be renting a car? Were you thinking of staying in Florence the whole time and doing day trips? Both are doable, but not having a car will influence what and where you can go.
As far as recommendations on where to stay, if you were to have a car I'd recommend staying outside of Florence's city center - if you don't, stay inside. Take a look at this pretty spectacular one, with parking, outside the center - it has great views over the city! It is also perfect for up to 4 guests.
The top-floor apartment with 2 terraces for you offers magnificent views of Florence and surroundings. Fully-equipped kitchen and two outdoor patio areas are ideal for dining alfresco, enjoying sunsets and views in complete privacy.

If you take a look at that site and see what appeals, if hotel or B&B or apartment, let me know and I can offer more specific suggestions!
If you're in Tuscany long enough, you could divide up some time in Florence with some time outside of the city, let's say in San Gimignano, a gorgeous medieval village, where you could then drive around the area exploring all of the other small towns in Chianti and Siena.
