The apartment is lovely and is in a great location for walking to everything. It has all of the things you need for a great stay in Florence.
Now for the not so good. Francesco did not respond to any communications once the booking was made, not even to provide check in or check out details. Also, even though I booked the apartment to use the sofa bed Francesco did not provide any bed linen. It took Airbnb Support to finally get a reply from him on providing this, and he advised he would only provide bed linen if the apartment was booked for 4 people. So don’t rely on using the sofa bed unless you are 4.
