The location of this apartment is unbeatable. In the middle of everything, at most 10 mins to all major points (including the train/bus station), but on a quiet street lined with high end stores which close for the night, so no crazy bar crowds till early morning. There is also a delicious cafe right down the street where we got our coffee. The host was very easy to communicate with and very responsive. Apartment was clean, the beds were very comfortable, mattresses are on the firmer side (which we loved). Having two en-suites was very nice. Overall our experience at the apartment was terrific.
One point to note, however, is that the third bathroom is tiny. Maybe 3 feet across, with the shower/toilet combination. You can see it in one of the photos, but I felt the photos didn't underscore just how small it is. A larger person would not fit. This was fine for us, since we only had to use the two en-suites.
Overall, I highly recommend this apartment and host, and will definitely consider staying again if/when we ever return to magnificent Florence.
