This was my first AirBNB experience and it was exceptional. The apartment is more spacious than it seems in the photos. The half bathroom connected to the bedroom is very convenient.
The location is excellent -- very close to all the tourist attractions, restaurants, shopping , etc... In spite of this, the apartment is very quite, and facing a charming court yard.
Paulo, the host, was super helpful -- he was always available for questions and booking taxis: his recommendations for places to see & to shop were excellent. He welcomed us, late in the evening, with wine and snacks, and made us feel very welcome.
I highly recommend this apartment for anyone who wants to spend some time in Florence.
