Pierpaolo and his apartment was without a doubt the best host and apartment we've stayed at using AirBnB.
Prior communication was 5-star. He also made suggestions and what to do during our stay. His recommendations led to us doing a cooking class and the Uffizi tour, both of which he booked and had vouchers waiting for us. He was seriously exceptional as a host.
The apartment is actually more spacious than the photos resemble. He's recently renovated the apartment so the bathroom, bedroom and kitchen are perfect and comfortable.
I wouldn't continue to search Airbnb for apartments in Florence if this is available, just book it. You won't be disappointed.
