We loved Sibilla's apartment- we stayed for two weeks and it was a wonderful little place to find comfort and relaxation at the end of a long and glorious day in Florence. The location is brilliant - removed from the intense tourist areas but easy walking distance to all of the sites in the city, every delicious restaurant, as well as grocery stores for extra supplies.
The apartment has everything you need, and Sibilla is very responsive to questions, as well as checking in to ensure everything was going smoothly.
I can't recommend this place highly enough and will definitely be back.
