What about enjoying Florence away from the noise and traffic, but near enough to reach them in a 20 minute walk? You can drive here safely, then leave your car and spend your time on public transport or on foot. When you get back, you'll find a fully furnished and equipped mini-apartment, with a shared kitchen and living room. This year I have had mosquito nets set on all windows: no nasty spirals and electric devices when you're lights are on!
Zagara is perfect also for long stays...
