A wonderful and special apt. Very comfortable, perfect for my sensibilities in every way. The neighborhood, the warm and tasteful feeling of the apt., the thoughtful suggestions of the host (some of which I tried and would have tried more if I'd been in Florence longer)... all good. Michele booked a taxi to pick me up for the airport--whether this would have been easy to do on my own or not (I don't speak Italian), I don't know, but I so appreciated that helpful gesture.
Be aware that there are 6 small/short flights of stairs--this might be an issue if you have a very large/heavy bag. But I personally would not let this issue prevent me from staying there again.
