Gabriella speaks fantastic English. Her ground-floor room is perfect. She greeted me on arrival and showed me the 5 keys needed to access the room (you know it is secure!) There is some graffiti outside around the piazza, but I never felt unsafe. Gabriella also advised me just to be back inside by 11pm. Just be aware of your surroundings, like any other big city.
There is a Nespresso-style coffee machine and a tea kettle in the room. Plenty of storage. Since I stayed near Christmas, she surprised me with a delicious panettone.
She also gave me plenty of suggestions on activities and restaurants nearby, all of which were delicious. Also, the Dante metro stop is only about 400m away from her house.
Her mother lives next to this room, and the couple of times I ran into her, she was also delightful.
Gabriella is easy to reach via text or WhatsApp; she was extremely responsive to all my questions.
I would love to stay with her again when I return to Napoli!
