Our stay in Massimo's apartment was fantastic! We would definitely recommend his apartment to anyone visiting Florence. The apartment is located very centrally and within walking distance to shops, a lot of nice cafes and restaurants, and all of the major attractions. It is also well-equiped with everything you will need for a comfortable stay, including cooking utensils, washing facilities, etc.
I can also say that we were surprised by how quiet the apartment was, despite its central location. Because the windows face a central courtyard, you won't hear any noise from the street. This is truly a rare find in the historical centre of medieval cities such as Florence.
