The apartment is even more beautiful than the pictures show. The ceilings are high, the rooms are spacious, the bath tub is deep, and THAT VIEW from the terrace is incredible. You can see Mount Vesuvius, Castel Sant Elmo, the park, and all of the beautiful homes of Napoli from one of two balconies.
Our host was Giovanni and he was wonderful. He met me and my friend at the apartment (note: it's off the main road, down the side street, and straight at the bottom of the hill. Pay attention to the signs and you can find it easily. The directions are clear, but Gogle Maps gets really confused and thinks the address is on the main street)
Giovanni gave us a great tour to ensure we knew how to use everything, where everything was located, and he gave us a million local recommendations! There is a supermarket down the street for you to pick up groceries.
We highly recommend you stay here. My group of 4 stayed here for a week and it was perfect for our needs.
