Their place is really near Naples Centrale terminal and Piazza Garibaldi metro station. A lot of gelaterias and pizzerias are nearby so there's a lot to see and eat. Duomo is about 5-7 minutes walk as well.
What we loved about the house is it was sparkly clean and has a pretty terrace upstairs. The bedroom and the kitchen were really nice. My mom would love to go back to Naples real soon because of it.
