We did not meet Francesco but his parents are friendly and welcoming. We did not see them very much since they are out most of the time and in any case there is independent, private access to the terrace and apartment by lift. The apartment is elegant and large with a huge roof terrace surrounded by flowers (even in March). It seemed very secure. Everything essential (and quite a bit more!) was supplied. The building is historic but the apartment has been sympathetically renovated with modern roof windows and lots of wood. The location is convenient, on the edge of the old city and within walking distance of shops, metro stations, the railway station and many historic churches and museums. There is a trolley-bus stop just opposite but we never used it because Naples is notably lacking in information about the public transport system (other than the metro). The area seemed pretty typical of the old (and most interesting) parts of the city - that is, crowded, poor, drab on the outside but with some delightful, indeed glorious, interiors.
