We (2 people) stayed one night in August.
The Apartment:
It is a polished, well-put together home. The classical decor is impeccable and beautiful. Everything was very clean. Plenty of space in main bedroom and sitting area. Bathroom is very clean with toiletries and towels available for the guests. The kitchen had supplies. The bed was very comfortable (extra pillows and blankets in the closet). AC (only on and off setting). Tourist guides available. I had no issues with the place, it was above my expectations. The large mural painting in the bedroom made me feel like I was sleeping in a museum or palace.
The Location:
Within walking distance of the train terminal. This is helpful when we have large luggage. The apartment is on the (European) second floor and we were not allowed to use the elevator because it was restricted to the residents with special need for it. Roberto was kind enough to carry my luggage up. My partner lugged up his larger one which was not fun for him after such a long trip in Italy thus far. Many sites were within walking distance.
The Host:
Roberto was very communicative via AirBnb app. We communicated to them our arrival time. Roberto showed up in-person, showed us around the apartment, showed us how to use the lock, checked our passports, went over a tourist map and gave restaurant recommendations, all in a friendly manner. He was also accommodating when we requested last minute to leave our luggage at the apartment a little longer after our check-out so we could soak in Florence a little more before our scheduled train trip (before we realized we could pay for luggage storage lockers nearby the terminal).
The Value:
We basically only utilized the bedroom and bathroom for a one night stay so this was a luxurious splurge for us. It would have been nice to have stayed longer. I would recommend for people who would utilize the amenities more like the kitchen and washer.
