The apartment of Francesco is actually a part of the Palazzo. It has an individual entrance, kitchen and private terrace. Although is quite old, it has everything you need for a few day stay. There is also a great pizza place just at the corner! :)
Its location is 5 minutes walk from Piazza Cavour which has 2 metro stations, so is well connected. The neighborhood Sanita it might be a bit unconfortable in the evening if you are travelling alone.
Unfortunately we didn't meet Francesco, but Mrs. Paola, his mother, was very welcoming and full of advices and suggestions of what to visit in Naples. She also gave us books regarding the monuments and magazines with things to see. She prepared a nice welcome drink accompanied with typical 'sfogliatelle'.
It was really nice to stay at Francesco's place!
