Federico is an attentive and considerate host. You can tell that he really wants you to have a fabulous time. He is easy to contact and will quickly fix any problems or answer questions.
The kitchen was better than I expected, it's easy to shop nearby and you can get great tasting italian ingredients. I got a coffee for less than €1. Eat the street food where the locals are eating for under €2 too.
It's easy to get in and out of central Naples, I did the free walking tours, but, if you're reasonable fit, I'd recommend exploring the area using the steps between the roads and the funiculars. (Be careful using Google maps, mine didn't recognize the funiculars so didn't recommend the best route.)
