We stayed a week and had a wonderful time. The apartment is very centrally located (just off Piazza della Liberta) and all the sights are 20-30 minute walk away. The apartment is very clean and comfortable (nice and cool in summer). There's also a modern kitchen and lovely shady outdoor terrace. The hosts are very welcoming and they were always very quick to respond to questions and queries. They even booked our taxi back to the airport. Great value for a short break in Florence!
