The first thing I want to mention before talking about the apartment, is how great the host is. She helped us with a mini guide of Firenze, showed us the best spots to ear, links to book different places to visit and she had a great energy.
The apartment was more beautiful than the pictures showed, it was very clean and cozy. Also, a very nice balcony to stay with your friends at night to drink a glass of wine and plan what to visit the next day.
Also, the apartment is close to the city center and the main spots to visit in Firenze and you can reach them by foot, but also staying in a very quiet neighborhood.
A very pleasant experience that I recommend 100%
