I highly recommend this listing.
Luisa's place is well-located, clean and tastefully furnished. There's AC in every room which was so soothing every time I returned to the flat. In addition, Luisa helped me with very useful tips for shopping and exploring the city, along with a map. This was particularly helpful for me; I actually walked the whole city on foot following the routes she marked on the map. I had a great experience staying there. I will stay again when I am back to Florence.
