We had a great stay at Enrico's flat. He's a really welcoming host, and the apartment is full of great touches: extra blankets, well-equipped kitchen, comfortable sofa.
We slept really well as the bed is good quality and made up with nice linens. It's a stylish place – and probably the cleanest Airbnb we have ever stayed in! – but also comfortable and relaxed so after a busy day sightseeing you can just flop down with a beer. We would recommend it if you're staying in Napoli!
