Giovanna and the whole family treated us warmly. They had a parking garage near the apartment and they parked the car for us (it cost 20 euros per night in cash). They didn't speak english but when using google translater we manged well so language barrier wasn't a problem.
Are is in the city centre, with small roads so I cam imagine it's difficult to find by yourself (they came to meet us for the square nearby) also roads are difficult to drive by car, but we managed to do it. You can feel real italian atmosphere here in this area and see how locals live (still it felt safe).
Apartment was exactly as we imagined, very tidy and suitable for couple (also downstairs there is a sofabed in case more than two staying). We got everything we need.
Area is quite noisy if you want a good night sleep, but it didn't bother us (use earplugs).
Napoli it worth to see! Thank you, if we ever come back to Napoli we definately going to stay here again.
