The location of the apartment is great and having breakfast on the balcony in the morning sun is truly amazing. This alone makes this apartment worth a stay! The kitchen is quite small and you'll only find the most necessary things in it (there were no bowls but soup plates, which worked fine for cereals).
The floor was a little bit damaged in 1-2 spots, but that didn't bother us too much. The one thing we weren't happy with was the room temperature. The apartment is not equipped with a normal heating system, all you have is an A/C, which can't rise the temperature in this big room on its own, and a radiant heater (actually there were 2, but one didn't work). During our stay the air temperature outside was around 17-18°C, so we would have loved to come home to a warm apartment, but unfortunately the rooms and the floor were quite cold at all times. So if you consider visiting Florence outside the summer season and it's important for you that you have a really warm home, you should maybe search for something else or at least bring a warm sweater with you. Apart from that we totally enjoyed our stay and can definitely recommend this apartment!
