Victoria was responsive over the phone, and was kind enough to let us check in at 1145 am. (I was traveling with my parents - and my dad is old). The apartment was clean. And, the apartment is located exactly where described, is easy to find (walking distance from Stazione Santa Maria Novella), and is close to plenty of nice Trattorias and restaurants.
If you are a light sleeper or have babies, please be aware that the market does tend to stay pretty lively. And you hear shops shutting up and setting up for the next day through the night.
The only thing (perhaps in her description already) is the deposit of Eur 100. Since I did not have a lot of money on me, Victoria was nice enough to accept Eur 100 and return Eur 80 (deduction for cleaning fee). But since Airbnb has a deposit option as well, perhaps this is not necessary on her part? Overall, amazing city, good host, and good experience.
