The place is clean, and had comfortable beds. You are some distance from public transportation, and Federica's instructions for reaching the building are helpful as the route recommended by Google Maps is quite long. There is a market nearby, but restaurant options in the immediate vicinity of the building are scarce. I went to one nearby that served good sandwiches (I did not try their other dishes), but it is a cash-only establishment. This is common in Naples.
Ask Federica about Massimo. Seemingly a friend of hers, he gave a car tour of Naples as well as a drive to and from Pompeii, which is fairly close, to me and some other guests. With splitting the cost, the drive (as well as a tour of Pompeii from a different guide) were very reasonable and not to be missed. Great activity for a couple/group of travellers.
Federica was very helpful and responsive to questions. I would recommend staying at her location without any hesitation.
