Francesca's apartment was perfect for us. Francesca met us at the apartment to show us in and let us know the necessary, including some good tips on eating and what to visit. The apartment is 2 mins walk from the train and bus station, 2 mins away from where a free walking tour starts, a 10 mins stroll to the Cattedrale Santa Maria del Fiore and everything else.
The apartment was perfectly comfortable, new mattress, a kitchen with a fridge and equipped to cook a quick dinner if you fancy a night in, and a newly fitted bathroom, all tastefully decorated.
The restaurant downstairs, Osteria Centopoveri (Francesca's recommendation) was superb, great pizzas but also lots of more interesting local dishes, including lobster with gnocchi, which was a winner. We went twice! There's another restaurant on the same street, Osteria Sostanza, I think, but you need to book in advance!
Will be glad to return one day!
