We stayed with Daniela in the off-season with our two kids (a baby and a toddler). Daniela truly is the perfect host, and staying at her place has been our favorite Airbnb experience so far. She is very helpful and friendly, but she also makes sure her guests have an adequate level of privacy/independence (she comes upstairs once a day to restock the breakfast so you may or may not run into her on a daily basis). Whatever questions or logistical concerns we had, she was happy to help out and provide solutions, from calling a cab when we left to guiding us to the nearest ATM or amazing pizzeria.
As for the actual place, it really is super. The location could not be more central, and the building is very neat (both clean and just lovely). We did not use the terrace as the weather was not quite warm enough, but even in the rain it was nice to have that small outside area. We didn't take advantage of the well-supplied kitchen for anything other than the breakfast that was provided, but it appeared fully stocked with pots, pans, and utensils, so one could easily stay-in and cook complete meals there. The rooms themselves were also nice. We shared one room with the four of us (Daniela provided a crib for the baby), and it did not feel cramped in any way.

We recommend this place to anyone wishing to have a pleasant and low-key stay in Napoli!
