My mum and I stayed here recently. Lovely little flat very conveniently located a 5-10 minute walk from the nearby tram line which connects you to the centre of Florence in around 20 minutes. There's a large shopping centre located right next to the tram station.
Very clean with a helpful information booklet in the property, WiFi, air con, microwave and a coffee machine (although there were no pods provided which was a bit of a shame).
Parking is free with an allocated space in a gated private parking area (when you arrive don't try and park between the narrow metal poles lining the parking spaces out front - you're in the wrong place and you'll scratch your car)!!
A word of advice - the parking space is on a very steep gradient so make sure you leave your car in gear when you park and your handbrake works!
