It's worth highlighting that this place is up six flights of stairs, so if you have mobility issues take note. That said, the flights aren't especially steep or long, and we got used to it pretty quickly.
Once you're up there, the condo is very nice. Neatly decorated, and well equipped with a decent kitchen, dishwasher, and clothes washer. Like many places in Italy there is no clothes drier. Use balcony drying lines or a drying rack in the bathroom (don't forget to turn on the radiator!)
We stayed there for a week and it's a great place from which to explore Florence. We were rarely more than a 20ish minute walk from anything we wanted to do in the city, and for longer excursions the train station (as well as a decently sized grocery store) are just around the corner.
Another big plus is that our host and his staff were very responsive. I added them on whats app and they respond quickly and helpfully to every request, and even let us check our luggage in early on our arrival day
