The view from the balcony is absolutely stunning! The Duomo is so large you feel as though you could reach out and touch it, and at night, when it's lit up, it's genuinely breath taking.
The location in Florence is absolutely perfect. We climbed to the top of the Duomo and we were able to see down to our balcony, which was so fun! You can see the Duomo from most of the city, which was helpful in guiding us home as we oriented ourselves.
The only thing that I would point out, the apartment was lacking hand soap and some basic kitchen essentials. The wifi was there, but pretty slow. From what we understand, wifi in Florence is slow in most places due to the amount of buildings and the thickness of the walls. We were also asked to clean the kitchen before we left, this is something that I do anywhere that I stay, but was a little alarming since I paid a cleaning fee.
Overall a good place to stay, with a great view in a central location. Great for sleeping and securely keeping your things
