Fellow Airbnb'ers - this place really is a gem. It is well worth the money and the massive bathtub with a view of amazing florence rooftops is top notch. Your host is super gracious and easy to contact, even when I had left keys with my wife shopping and needed to rush back, they answered their door and were able to let me in and call ahead to have the apartment door unlocked. You won't be out of help if anything goes south.
As they make clear you will need internet access to first get in, which proved a little difficult for us as we didnt have any sim cards. But once we were in it was all good.The only issues we had were little things like a stain on the orange blanket on the bed, a lack of hot water, dirty kitchen utensils and bowls, and the wifi stopped working at 10pm on our last night which just hampered our ability to find our departure details which was a little scary.
Those were the only issues what so ever, and they didnt dampen the stay at all. It is worth it!
