Ahead of our journey Giuseppe exchanged plenty of text messages with us to make sure that we arrive safely and on time, which reflects a great sense of communication. Once we arrived at the location we drove past the entrance, not because we couldn't find it but rather because it is located in a road curve and people tend to speed on Neapolitan streets!
There's enough space infront of the entrance to park the car for a moment and figure out how to open the gate. Once we did that (just press the button with the call sign and someone will let you in) we were let in to drive a seemingly infinite alley overlooking Napoli to get a glimpse of what will await us for the next few days. At the end of the street, several parking spots and Guiseppe's Dad welcomed us (actually we've never met Guiseppe in person, just his dad) and introduced us to the place and all the safety rules. The building hosts several apartments and rooms, which are also partially rented via Airbnb.
The apartment itself offers all the equipment you'll need for a stay in a southern Italian city during midsummer days: AC, wine, breakfast, water, AC, an equipped kitchen, bathtub, comfortable bed, AC, and of course: the beautiful, beautiful view over Napoli (and AC). It is truly amazing, especially at night (not kidding!!).
Being situated on a hill though means you'd need some time to get to the city's downtown area (approx. 30min walk) or to the next metro station ( 20min walk). Overall, I'd recommend this place for couples and families as you'd have all the amenities you'd need to have a comfortable retreat.
P.S.: I got engaged on this very balcony with live music from the nearby venue and a full moon lightening up the Vesuv in the background while overlooking Napoli at night with tons of fireworks. It is definitely a special balcony!
