Luca's place was perfect for a stay just far enough from the busy, touristy streets of Florence, but near enough to conveniently visit the sites. There are a couple of bus routes to choose from, though their schedules and timings can be quite erratic, it just depends on your luck.
The flat itself was spacious, clean and well equipped. There was a fully equipped kitchen (fridge, oven, stove etc.), a strong hairdryer, and even a fan for when the flat got a little too hot.
Luca was a wonderful host who was friendly, always helpful and reachable. He recommended this lovely restaurant nearby which was by far the best meal we had in Florence (arguably better than La Buchetta, real local goodness).
Overall, it was a wonderful stay, and if in Florence would definitely stay again.
