You can't beat this place! Beautiful big clean apartment literally 100 yards from the Duomo- the photo says it all. I had. Booked for 8 days and as soon as I arrived, I extended for 3 more. The apartment is in an old palace- although the apartment is modern. The place has everything you need including fast WiFi, kitchenette with microwave and even a wash machine.
The location is incredible as the train station is only a 20 minute walk and everything else is very close by (central Florence is very compact). Lots of good coffee shops, bars and restaurants near by also. Naim was always available and texted me every few days to see if I needed anything. Highly recommended!
