We stayed at Elisabetta's apparment for 5 days. For two adults and two kids it suited us perfectly. The flat is renovated and has everything you might need.
But surely the best part is the location.
Situated next to Uffizi gallery we were into a walking distance from everything.
You can go out - do some sightseeing, come back rest a bit and repeat...
Florence is also very beautiful in the evening. We enjoy the night walks around the river and listened to live music around Uffizi.
