The Giovannini family are lovely friendly people and the apartment is spotlessly clean and very comfortable. The location is very much a local neighborhood but it feels safe and friendly. For us it was an easy and pleasant stroll into town (40mins) but the R4 bus is super simple and cheap also.
Napoli is great, a vibrant and interesting city with so many superb day trips nearby.
Our only regret was not having more interaction with Maria and her family (I was sick for our whole stay so we were pretty quiet).
Overall we felt comfortable and welcome and we would not hesitate to stay here again. Delightful hosts.
