We stayed a week in Francesca's flat. At our arrival Francesca's father showed us the place. We don't speak Italian but managed to communicate through a mix of french, spanish and little italian vocabulary.

The description of the flat is accurate. It is in fact very spacious and the terrace is nice.
Unfortunately for us, the fridge was not working at our arrival and it took 5 days to be fixed. Naples is very very hot in the summer and without a fridge and no air condition ( only an old fan in the bedroom ) it has been a bit hard to relax and rest at home.
The neighborhood is nice, you can hang in all the narrow streets full of life and scooters (take care). If you are not much into walking, be aware that the flat is a bit uphill. The pizza down the flat is good and cheap. Concerning its location, it is true that the flat is between the different areas of the city but you need to count 25 minutes walk to piazza Bellini, 40 to archeological museum, 40 to the ferries. İt's doable but with the heat, a taxi is sometimes necessary.

Francesca texts and Francesca's father were very nice and gentle but this situation with the fridge made us feel a bit awkward. We thought it would be fixed faster, Francesca's father offered us to use his fridge (unfortunately he was not always hearing when we knocked at his door), 20 euros and grapes but it was not really what we were waiting for. As well, asking us to be at home at 6pm for the repairer (because Francesca's father had not the key of the flat) whereas the repairer did not come was not great. A phone call, few tips and informations (where to find a supermarket for example) would have been more accurate.

Overall, I could recommend this flat, but not during hot times and to people ready for quite long promenades through the city.
