Giovanni has clearly put a lot of thought into decorating and furnishing this room. It is big, light, clean, and well appointed. The kitchen has everything you need, including filter coffee, condiments, and olive oil if you decide to cook (although eating out in Naples is so cheap it hardly seems worth the effort!). Communicating with Mamma Angela is difficult if you can't speak Italian, particularly if you go beyond 'here is the key, this is the fridge', but Giovanni is easy to contact in case of difficulty, and he is quick to respond.
There are some comments from previous reviewers about the neighbourhood, so here is a top travel tip: if there are single women and elderly couples walking around, you're probably going to be ok! This is inner-city Naples, and the price you pay for convenient transport links to Pompeii & Herculaneum, and easy access to the old city, is the chaos that is Metropolitan Italy - where people, cars and scooter hurtle around like cats on crack. Like any inner city location, there is a risk of petty theft - be alert for pickpockets and moped thieves, and you won't have any problems. The apartment itself is very secure, and suited our purposes perfectly. With the windows and blinds closed at night, we weren't bothered by street noise.
