Location is great! so close to everything, yet peaceful (french windows are open to countryard). I loved the yard garden and tastful design of the flat. Flat is great for 2-4 or a family. Beware, there is no washingmachine in the flat (or Im blind:-). The communication with owner might be little confusing as the messages are in italian. But nothing that google translator can not solve.
The neighbourhod is traditional neapoletan lively one...with tiny shops, local eateries, hanging laundry and nice people. Try great margharita for just 3 EUR (Pizzeria Pavia) or sfogliatela for breakfast.
There is much to do in naples! from what we saw I really reccomend san gennaro catacombes.
