Apartment is great! Location is perfect -everything you want to see is really close.
Apartment looks like a theater with a lot of interesting things inside. One can spend a day just watching at this things. The only issue was really slow internet which you don't really need cos you'll spend all day walking in galleries :) Fabrizio was very friendly and even met us at the train station. Really good choice if you need an apartment for 2-4 people in Florence!
