Stefano's apartment might just be in the best location in the entire city. Piazza Santo Spirito is truly a nightlife mainstay with some great restaurants and super close to the historic city center.
The balcony is also one of the best I have seen in the city. We basically spent all our evenings home on the terrace, enjoying the view and the fantastic Florentine atmosphere!
I would absolutely recommend this apartment to anyone who enjoys a fabulous location, amazing terrace and air conditioning (trust me, you will ;-) )!
