Francesco's place is well situated in the center of the city, near shops, markets, restaurants and most importantly, all the main attractions (Il Duomo, piazza della Signoria, Uffizi and Palazzo Vechio piazza San Lorenzo, Santa Croce, Medici Chapel and Palace, Mercato Centrale, the Arno River and Ponte Vechio- basically everything you want to visit). We didn't need bus or tram tickets since everything is on a walking distance from Francesco's apartment. From the airport you can arrive easily since there is a tram line (T2) directly to the city center, and then you can take a bus or just walk for about 10 minutes.
Since we arrived with a delay, later than we expected, the host was kind to leave the keys for us and detailed instructions how to get in. The apartment is spacious enough to accommodate 4 persons and clean. The place is just like in the pictures and you will find everything you need for your stay. Extra sheets were kindly provided by the host and the coffee and water were a nice touch also. We also went to some of the food suggestions from Francesco's list and were not disappointed. I recommend this listing because both Francesco and Cristiana were quick to respond all of my questions and they just give you a nice vibe, you feel welcomed in their place.
To sum up, everything is great about the place, the location and the host. You won't regret choosing the apartment.
We had a fantastic time and would definitely come back with the first occasion.
