The apartment is located in the heart of Florence. Almost all attractions are in 500m walking distance. You only need 2-3 min to stand right in front of to the Cathedral Santa Maria del Fiore. We enjoyed walking next to the Cathedral from and to the apartment as there is such a great atmosphere, especially at night.
Just be aware - as the apartment is so central - it is also noise from surrounding restaurants and construction sides during our visit. But it is not too bad and the central location made more than up for it.
