This apartment is absolutely beautiful. After many Airbnb experiences, I was impressed that it looked exactly as it did in pictures - no hidden surprises! It's beautifully appointed - it was so nice to wake up those surroundings each morning. It was also spotless with very nice bathrooms and a good shower.
The location is fantastic - we have spent a lot of time in Florence, and this is one of the best locations we have stayed in. It was so fun to look over the balcony and see all of the activity in the Piazza della Signoria below. There are also a few cafes right downstairs - touristy, but nice if you want to grab a quick coffee or pastry before you start walking. You are steps away from all of the major attractions, but also close to the Oltrarno, which is nice.
Check in was super easy, Stefano was really accommodating even though we were caught in traffic and arrived a little later than expected, and he was very nice and helpful. He was also flexible about check out, offering to let us leave our bags for a couple of ours while the apartment was cleaned for the next guests.
A few notes - it can be very noisy on the piazza at night, so if you are a light sleeper this might bother you. It was fine on the weeknights we were there, but the weekend was a bit loud. It wouldn't prevent me from staying again. Also, make sure you pack your own toiletries, we had to run out to buy shampoo and body wash.
Overall, a great stay - I definitely recommend this apartment!
